Origins Of Hutu, Tutsi And Twa
The origins of the Hutu and Tutsi people is a major controversial issue in the histories of Rwanda and Burundi, as well as the Great Lakes region of Africa. The relationship between the two modern populations is thus, in many ways, derived from the perceived origins and claim to "Rwandan-ness". The largest conflicts related to this question were the Rwandan genocide, the Burundian genocide (Hutu and Tutsi), and the First and Second Congo Wars. Ugandan scholar Mahmoud Mamdani identifies at least four distinct foundations for studies that support the "distinct difference between Hutu and Tutsi" school of thought: phenotype and genotype, cultural memory of inhabitants of Rwanda, archeology, and linguistics. Most Tutsis and Hutus carry the E1b1b and E1b1a paternal haplogroup, where E1b1a is common among Bantu populations; E1b1b is common among Afroasiatic populations. Genetic studies More recent studies have de-emphasized physical appearance, such as height and nose width, in favor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hutu
The Hutu (), also known as the Abahutu, are a Bantu ethnic or social group which is native to the African Great Lakes region. They mainly live in Rwanda, Burundi and the eastern Democratic Republic of the Congo, where they form one of the principal ethnic groups alongside the Tutsi and the Great Lakes Twa. Demographics The Hutu is the largest of the three main population divisions in Burundi and Rwanda. Prior to 2017, the CIA World Factbook stated that 84% of Rwandans and 85% of Burundians are Hutu, with Tutsis being the second largest ethnic group at 15% and 14% of residents of Rwanda and Burundi, respectively. However, these figures were omitted in 2017 and no new figures have been published since then. The Twa pygmies, the smallest of the two countries' principal populations, share language and culture with the Hutu and Tutsi. They are distinguished by a considerably shorter stature. Origins The Hutu are believed to have first emigrated to the Great Lake re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sickle Cell Trait
Sickle cell trait describes a condition in which a person has one abnormal allele of the hemoglobin beta gene (is heterozygous), but does not display the severe symptoms of sickle cell disease that occur in a person who has two copies of that allele (is homozygous). Those who are heterozygous for the sickle cell allele produce both normal and abnormal hemoglobin (the two alleles are codominant with respect to the actual concentration of hemoglobin in the circulating cells). Sickle cell disease is a blood disorder wherein there is a single amino acid substitution in the hemoglobin protein of the red blood cells, which causes these cells to assume a sickle shape, especially when under low oxygen tension. Sickling and sickle cell disease also confer some resistance to malaria parasitization of red blood cells, so that individuals with sickle-cell trait (heterozygotes) have a selective advantage in environments where malaria is present. Symptoms and signs Sickle cell trait is a hemo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bantu Peoples
The Bantu peoples, or Bantu, are an ethnolinguistic grouping of approximately 400 distinct ethnic groups who speak Bantu languages. They are native to 24 countries spread over a vast area from Central Africa to Southeast Africa and into Southern Africa. There are several hundred Bantu languages. Depending on the definition of "language" or "dialect", it is estimated that there are between 440 and 680 distinct languages. The total number of speakers is in the hundreds of millions, ranging at roughly 350 million in the mid-2010s (roughly 30% of the population of Africa, or roughly 5% of the total world population). About 60 million speakers (2015), divided into some 200 ethnic or tribal groups, are found in the Democratic Republic of the Congo alone. The larger of the individual Bantu groups have populations of several million, e.g. the people of Rwanda and Burundi (25 million), the Bagandapeople of Uganda (10 million as of 2019), the Shona of Zimbabwe (15 million ), the Zulu of ...

Y Chromosome
The Y chromosome is one of two sex chromosomes (allosomes) in therian mammals, including humans, and many other animals. The other is the X chromosome. Y is normally the sex-determining chromosome in many species, since it is the presence or absence of Y that determines the male or female sex of offspring produced in sexual reproduction. In mammals, the Y chromosome contains the gene SRY, which triggers male development. The DNA in the human Y chromosome is composed of about 59 million base pairs, making it similar in size to chromosome 19. The Y chromosome is passed only from father to son. With a 30% difference between humans and chimpanzees, the Y chromosome is one of the fastest-evolving parts of the human genome. The human Y chromosome carries an estimated 100–200 genes, with between 45 and 73 of these being protein-coding. All single-copy Y-linked genes are hemizygous (present on only one chromosome) except in cases of aneuploidy such as XYY syndrome or XXYY syndrome. ...

Bethwell Ogot
Bethwell Allan Ogot (born 1929) is a historian from Kenya. He specialises in African history, research methods and theory. One of his works starts by saying that "to tell the story of a past so as to portray an inevitable destiny is, for humankind, a need as universal as tool-making. To that extent, we may say that a human being is, by nature, historicus. He was the Chancellor of Moi University up to early 2013. Biography Ogot, a Kenyan Luo, was born in Gem Location of Siaya County of Kenya. In 1959 he married Grace Emily Akinyi, a politician, writer and health specialist. She eventually served the government of Kenya as an Assistant Minister for Culture and Social Services. He was educated at Ambira, Maseno School, Makerere University College, and the University of St Andrews and the School of Oriental and African Studies, University of London. While studying in London, he served as a leader of the Kenya Students Association, where he assisted the Kenya nationalist ...

Shi Language
Shi, or Nyabungu, is a Bantu language of the Democratic Republic of the Congo. The Nyindu variety is heavily influenced by Lega, and speakers consider it a dialect of Lega rather than Shi, as Shi speakers see it. Maho (2009) leaves it unclassified as JD.501. The people who speak Mashi are known as Bashi. They are the largest tribe in South Kivu, whose capital city is Bukavu Bukavu is a city in eastern Democratic Republic of the Congo (DRC), lying at the extreme south-western edge of Lake Kivu, west of Cyangugu in Rwanda, and separated from it by the outlet of the Ruzizi River. It is the capital of the South Kivu pr .... The Bashi occupy a vast region known as Bushi.

Milk
Milk is a white liquid food produced by the mammary glands of mammals. It is the primary source of nutrition for young mammals (including breastfed human infants) before they are able to digestion, digest solid food. Immune factors and immune-modulating components in milk contribute to milk immunity. Early-lactation milk, which is called colostrum, contains antibody, antibodies that strengthen the immune system, and thus reduces the risk of many diseases. Milk contains many nutrients, including protein and lactose. As an agricultural product, dairy milk is Milking, collected from farm animals. In 2011, Dairy farming, dairy farms produced around of milk from 260 million dairy cows. India is the world's largest producer of milk and the leading exporter of skimmed milk powder, but it exports few other milk products. Because there is an ever-increasing demand for dairy products within India, it could eventually become a net importer of dairy products. New Zealand, Germany and the ...

Lactose
Lactose is a disaccharide sugar synthesized by galactose and glucose subunits and has the molecular formula C12H22O11. Lactose makes up around 2–8% of milk (by mass). The name comes from ' (gen. '), the Latin word for milk, plus the suffix '' -ose'' used to name sugars. The compound is a white, water-soluble, non-hygroscopic solid with a mildly sweet taste. It is used in the food industry. Structure and reactions Lactose is a disaccharide derived from the condensation of galactose and glucose, which form a β-1→4 glycosidic linkage. Its systematic name is β-D-galactopyranosyl-(1→4)-D-glucose. The glucose can be in either the α-pyranose form or the β-pyranose form, whereas the galactose can only have the β-pyranose form: hence α-lactose and β-lactose refer to the anomeric form of the glucopyranose ring alone. Detection reactions for lactose are the Woehlk- and Fearon's test. Both can be easily used in school experiments to visualise the different lactose content o ...

Malaria
Malaria is a mosquito-borne infectious disease that affects humans and other animals. Malaria causes symptoms that typically include fever, tiredness, vomiting, and headaches. In severe cases, it can cause jaundice, seizures, coma, or death. Symptoms usually begin ten to fifteen days after being bitten by an infected mosquito. If not properly treated, people may have recurrences of the disease months later. In those who have recently survived an infection, reinfection usually causes milder symptoms. This partial resistance disappears over months to years if the person has no continuing exposure to malaria. Malaria is caused by single-celled microorganisms of the ''Plasmodium'' group. It is spread exclusively through bites of infected ''Anopheles'' mosquitoes. The mosquito bite introduces the parasites from the mosquito's saliva into a person's blood. The parasites travel to the liver where they mature and reproduce. Five species of ''Plasmodium'' can infect and be spread by h ...
