Pingelap
Pingelap is an atoll in the Pacific Ocean, part of Pohnpei State of the Federated States of Micronesia, consisting of three islands: Pingelap Island, Sukoru and Daekae, linked by a reef system and surrounding a central lagoon, although only Pingelap Island is inhabited. The entire system has a land area of 1.8 km² (455 acres) at high-tide, and is less than at its widest point. The atoll has its own language, Pingelapese, spoken by most of the atoll's 250 residents. History The first European observer of the islands was Captain Thomas Musgrave in the ship . Captain MacAskill in revisited them in 1809. Errors in measurement of their location resulted in the islands being separately named on charts in the 19th century as the Musgrave Islands and the MacAskill islands, within the Caroline archipelago. Historically, the ''Ouwa'' or the Paramount Chief or King of Pikelap which is a hereditary title that granted supreme rule of the land, ruled the island of Pikelap which is n ...

Pingelapese Language
The Pingelapese language is a Micronesian language native to Pingelap, an atoll belonging to the state of Pohnpei in the Federated States of Micronesia. This atoll is the homeland to the Pingelapese people, consisting of a three-square mile range of uninhabited small coral islets, Daekae and Sukora, and the inhabited islet, Pingelap. These islands partially make up the Caroline Islands. Because of natural disasters and emigration consequent to European and U.S. influence, the local population of the Pingelapese people is small. There are at least 2,000 Pingelapese people worldwide. Although the official language of the Pohnpei State is English, 200 of the 250 Pingelap atoll residents and 1,200 Pohnpei residents speak Pingelapese. The Pingelapese language is used for face-to-face communication among speakers of all ages. It is classified as a vigorous language. With the help of linguists like Leilani Welley-Biza sharing knowledge from her elders, significant cultural/historical ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Federated States Of Micronesia
The Federated States of Micronesia (; abbreviated FSM) is an island country in Oceania. It consists of four states from west to east, Yap, Chuuk, Pohnpei and Kosraethat are spread across the western Pacific. Together, the states comprise around 607 islands (a combined land area of approximately ) that cover a longitudinal distance of almost just north of the equator. They lie northeast of Indonesia and Papua New Guinea, south of Guam and the Marianas, west of Nauru and the Marshall Islands, east of Palau and the Philippines, about north of eastern Australia, 3,400 km (2,133 mi) southeast of Japan, and some southwest of the main islands of the Hawaiian Islands. While the FSM's total land area is quite small, the country's waters occupy more than of the Pacific Ocean, giving the country the 14th-largest exclusive economic zone in the world. The sovereign island nation's capital is Palikir, located on Pohnpei Island, while the largest city is Weno, loca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Achromatopsia
Achromatopsia, also known as Rod monochromacy, is a medical syndrome that exhibits symptoms relating to five conditions, most notably monochromacy. Historically, the name referred to monochromacy in general, but now typically refers only to an autosomal recessive congenital color vision condition. The term is also used to describe cerebral achromatopsia, though monochromacy is usually the only common symptom. The conditions include: monochromatic color blindness, poor visual acuity, and day-blindness. The syndrome is also present in an ''incomplete'' form that exhibits milder symptoms, including residual color vision. Achromatopsia is estimated to affect 1 in 30,000 live births worldwide. Signs and symptoms The five symptoms associated with achromatopsia are: # Color blindness - usually monochromacy # Reduced visual acuity - uncorrectable with lenses # Hemeralopia – with the subject exhibiting photophobia # Nystagmus # Iris operating abnormalities The syndrom ...

Pohnpei State
Pohnpei State (IPA: pɔ:n peɪ) is one of the four states of the Federated States of Micronesia (FSM). The other states are, from east to west, Kosrae State, Chuuk State, and Yap State. The state's main island is Pohnpei. History The pre-colonial history of Pohnpei is divided into three stages: Mwehin Kawa or Mwehin Aramas (ca. 1100); Mwehin Sau Deleur (from ca. 1100 to ca. 1628); and Mwehin Nahnmwarki (from ca. 1628 to ca. 1885). In Pohnpei there are interesting ruins of a Micronesian civilization, especially the ruins of Nan Madol. Spanish Colonization The Caroline Islands, within which the island of Pohnpei is currently included, were visited on 22 August 1526 by the Spanish explorer Toribio Alonso de Salazar. On 1 January 1528, the explorer Alonso de Saavedra took possession of the islands of Uluti in the name of the King of Spain. The archipelago was visited in 1542, by the Matelotes Islands in 1543 and 1545, and by Legazpi in 1565. The first European visitor to Ponap� ...

Caroline Islands
The Caroline Islands (or the Carolines) are a widely scattered archipelago of tiny islands in the western Pacific Ocean, to the north of New Guinea. Politically, they are divided between the Federated States of Micronesia (FSM) in the central and eastern parts of the group, and Palau at the extreme western end. Historically, this area was also called ''Nuevas Filipinas'' or New Philippines, because they were part of the Spanish East Indies and were governed from Manila in the Philippines. The Carolines are scattered across a distance of approximately 3,540 kilometers (2,200 miles), from the westernmost island, Tobi, in Palau, to the easternmost island, Kosrae, a state of the FSM. Description The group consists of about 500 small coral islands, east of the Philippines, in the Pacific Ocean. The distance from Yap (one of the larger Caroline islands) to Manila is . Most of the islands are made up of low, flat coral atolls, but there are some that rise high above se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Founder Effect
In population genetics, the founder effect is the loss of genetic variation that occurs when a new population is established by a very small number of individuals from a larger population. It was first fully outlined by Ernst Mayr in 1942, using existing theoretical work by those such as Sewall Wright. As a result of the loss of genetic variation, the new population may be distinctively different, both genotypically and phenotypically, from the parent population from which it is derived. In extreme cases, the founder effect is thought to lead to the speciation and subsequent evolution of new species. In the figure shown, the original population has nearly equal numbers of blue and red individuals. The three smaller founder populations show that one or the other color may predominate (founder effect), due to random sampling of the original population. A population bottleneck may also cause a founder effect, though it is not strictly a new population. The founder effect occu ...

Pohnpei
Pohnpei "upon (''pohn'') a stone altar (''pei'')" (formerly known as Ponape or Ascension, Proto-Chuukic-Pohnpeic: ''*Fawo ni pei)'' is an island of the Senyavin Islands which are part of the larger Caroline Islands group. It belongs to Pohnpei State, one of the four states in the Federated States of Micronesia (FSM). Major population centers on Pohnpei include Palikir, the FSM's capital, and Kolonia, the capital of Pohnpei State. Pohnpei Island is the largest with an area of , and a highest point of , the most populous with 36,832 people, and the most developed single island in the FSM. Pohnpei is home to the megaliths and ruined city of Nan Madol, built of artificial islands off the island's eastern shore beginning in the 8th or 9th century. An important archaeological site, it was declared a national historic site in 1985. Pohnpei contains a wealth of biodiversity. It is one of the wettest places on Earth with annual recorded rainfall exceeding each year in certai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geneticist
A geneticist is a biologist or physician who studies genetics, the science of genes, heredity, and variation of organisms. A geneticist can be employed as a scientist or a lecturer. Geneticists may perform general research on genetic processes or develop genetic technologies to aid in the pharmaceutical or and agriculture industries. Some geneticists perform experiments in model organisms such as ''Drosophila'', ''C. elegans'', zebrafish, rodents or humans and analyze data to interpret the inheritance of biological traits. A basic science geneticist is a scientist who usually has earned a PhD in genetics and undertakes research and/or lectures in the field. A medical geneticist is a physician who has been trained in medical genetics as a specialization and evaluates, diagnoses, and manages patients with hereditary conditions or congenital malformations; and provides genetic risk calculations and mutation analysis. Education Geneticists participate in courses from many area ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inbreeding
Inbreeding is the production of offspring from the mating or breeding of individuals or organisms that are closely related genetically. By analogy, the term is used in human reproduction, but more commonly refers to the genetic disorders and other consequences that may arise from expression of deleterious or recessive traits resulting from incestuous sexual relationships and consanguinity. Animals avoid incest only rarely. Inbreeding results in homozygosity, which can increase the chances of offspring being affected by recessive traits. In extreme cases, this usually leads to at least temporarily decreased biological fitness of a population (called inbreeding depression), which is its ability to survive and reproduce. An individual who inherits such deleterious traits is colloquially referred to as ''inbred''. The avoidance of expression of such deleterious recessive alleles caused by inbreeding, via inbreeding avoidance mechanisms, is the main selective reason for outcros ...

Gene Pool
The gene pool is the set of all genes, or genetic information, in any population, usually of a particular species. Description A large gene pool indicates extensive genetic diversity, which is associated with robust populations that can survive bouts of intense selection. Meanwhile, low genetic diversity (see inbreeding and population bottlenecks) can cause reduced biological fitness and an increased chance of extinction, although as explained by genetic drift new genetic variants, that may cause an increase in the fitness of organisms, are more likely to fix in the population if it is rather small. When all individuals in a population are identical with regard to a particular phenotypic trait, the population is said to be 'monomorphic'. When the individuals show several variants of a particular trait they are said to be polymorphic. History The Russian geneticist Alexander Sergeevich Serebrovsky first formulated the concept in the 1920s as ''genofond'' (gene fund), ...

Health Care
Health care or healthcare is the improvement of health via the prevention, diagnosis, treatment, amelioration or cure of disease, illness, injury, and other physical and mental impairments in people. Health care is delivered by health professionals and allied health fields. Medicine, dentistry, pharmacy, midwifery, nursing, optometry, audiology, psychology, occupational therapy, physical therapy, athletic training, and other health professions all constitute health care. It includes work done in providing primary care, secondary care, and tertiary care, as well as in public health. Access to health care may vary across countries, communities, and individuals, influenced by social and economic conditions as well as health policies. Providing health care services means "the timely use of personal health services to achieve the best possible health outcomes". Factors to consider in terms of health care access include financial limitations (such as insurance cove ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Autosomal Recessive
In genetics, dominance is the phenomenon of one variant ( allele) of a gene on a chromosome masking or overriding the effect of a different variant of the same gene on the other copy of the chromosome. The first variant is termed dominant and the second recessive. This state of having two different variants of the same gene on each chromosome is originally caused by a mutation in one of the genes, either new (''de novo'') or inherited. The terms autosomal dominant or autosomal recessive are used to describe gene variants on non-sex chromosomes ( autosomes) and their associated traits, while those on sex chromosomes (allosomes) are termed X-linked dominant, X-linked recessive or Y-linked; these have an inheritance and presentation pattern that depends on the sex of both the parent and the child (see Sex linkage). Since there is only one copy of the Y chromosome, Y-linked traits cannot be dominant or recessive. Additionally, there are other forms of dominance such as in ...
