Margaret Kidwell
Margaret Gale Kidwell (born August 17, 1933) is a British American evolutionary biologist and Regents’ Professor Emerita at the University of Arizona, Tucson. She grew up on a farm in the English Midlands during World War II. After graduating from the University of Nottingham in 1953, she worked in the British Civil Service as an Agricultural Advisory Officer from 1955-1960. She moved to the US in 1960 under the auspices of a Kellogg Foundation Fellowship to study Genetics and Statistics at Iowa State University. She married quantitative geneticist James F. Kidwell in 1961, obtained her MS degree in 1962 and moved with her husband to Brown University in 1963. She received her PhD from Brown University in 1973 under the guidance of Masatoshi Nei. From 1973 to 1984 she pursued independent research into a number of anomalous genetic phenomena in ''Drosophila'' which later lead to collaborative studies resulting in the discovery of hybrid dysgenesis and the isolation of transposable ...

British-American
British American usually refers to Americans whose ancestral origin originates wholly or partly in the United Kingdom (England, Scotland, Wales, Northern Ireland, Cornwall, Orkney, and the Isle of Man). It is primarily a demographic or historical research category for people who have at least partial descent from peoples of Great Britain and the modern United Kingdom, i.e. English, Scottish, Welsh, Scotch-Irish, Orcadian, Manx and Cornish Americans. Based on 2020 American Community Survey estimates, 1,934,397 individuals identified as having British ancestry, while a further 25,213,619 identified as having English ancestry, 5,298,861 Scottish ancestry and 1,851,256 Welsh ancestry. The total of these groups, at 34,298,133, was 10.5% of the total population. A further 31,518,129 individuals identified as having Irish ancestry, but this is not differentiated between modern Northern Ireland and the Republic of Ireland. Figures for Manx and Cornish ancestries are not separately ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Genetic Association
The American Genetic Association (AGA) is a USA-based professional scientific organization dedicated to the study of genetics and genomics which was founded as the American Breeders' Association in 1903. The association has published the '' Journal of Heredity'' since 1914, which disseminates peer-reviewed organismal research in areas of general interest to the genetics and genomics community. Recent articles have focused on conservation genetics of endangered species and biodiversity discovery, phylogenomics, molecular adaptation and speciation, and genotype to phenotype associations. History The American Breeders Association held its first meeting in 1903 to discuss the “new” science of genetics that arose from Charles Darwin’s theory of evolution and Gregor Mendel’s discoveries of the laws of inheritance. The organization was established “to study the laws of breeding and to promote the improvement of plants and animals by the development of expert methods of breeding ...

Iowa State University Alumni
Iowa () is a state in the Midwestern region of the United States, bordered by the Mississippi River to the east and the Missouri River and Big Sioux River to the west. It is bordered by six states: Wisconsin to the northeast, Illinois to the east and southeast, Missouri to the south, Nebraska to the west, South Dakota to the northwest, and Minnesota to the north. During the 18th and early 19th centuries, Iowa was a part of French Louisiana and Spanish Louisiana; its state flag is patterned after the flag of France. After the Louisiana Purchase, people laid the foundation for an agriculture-based economy in the heart of the Corn Belt. In the latter half of the 20th century, Iowa's agricultural economy transitioned to a diversified economy of advanced manufacturing, processing, financial services, information technology, biotechnology, and green energy production. Iowa is the 26th most extensive in total area and the 31st most populous of the 50 U.S. states, with a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

University Of Arizona Faculty
A university () is an institution of higher (or tertiary) education and research which awards academic degrees in several academic disciplines. ''University'' is derived from the Latin phrase ''universitas magistrorum et scholarium'', which roughly means "community of teachers and scholars". Universities typically offer both undergraduate and postgraduate programs. The first universities in Europe were established by Catholic Church monks. The University of Bologna (), Italy, which was founded in 1088, is the first university in the sense of: *being a high degree-awarding institute. *using the word ''universitas'' (which was coined at its foundation). *having independence from the ecclesiastic schools and issuing secular as well as non-secular degrees (with teaching conducted by both clergy and non-clergy): grammar, rhetoric, logic, theology, canon law, notarial law.Hunt Janin: "The university in medieval life, 1179–1499", McFarland, 2008, , p. 55f.de Ridder-Symoens, Hild ...

Women Evolutionary Biologists
A woman is an adult female human. Prior to adulthood, a female human is referred to as a girl (a female child or adolescent). The plural ''women'' is sometimes used in certain phrases such as " women's rights" to denote female humans regardless of age. Typically, women inherit a pair of X chromosomes, one from each parent, and are capable of pregnancy and giving birth from puberty until menopause. More generally, sex differentiation of the female fetus is governed by the lack of a present, or functioning, SRY-gene on either one of the respective sex chromosomes. Female anatomy is distinguished from male anatomy by the female reproductive system, which includes the ovaries, fallopian tubes, uterus, vagina, and vulva. A fully developed woman generally has a wider pelvis, broader hips, and larger breasts than an adult man. Women have significantly less facial and other body hair, have a higher body fat composition, and are on average shorter and less muscular th ...

21st-century American Biologists
The 1st century was the century spanning AD 1 (Roman numerals, I) through AD 100 (Roman numerals, C) according to the Julian calendar. It is often written as the or to distinguish it from the 1st century BC (or BCE) which preceded it. The 1st century is considered part of the Classical era, epoch, or History by period, historical period. The 1st century also saw the Christianity in the 1st century, appearance of Christianity. During this period, Europe, North Africa and the Near East fell under increasing domination by the Roman Empire, which continued expanding, most notably conquering Britain under the emperor Claudius (AD 43). The reforms introduced by Augustus during his long reign stabilized the empire after the turmoil of the previous century's civil wars. Later in the century the Julio-Claudian dynasty, which had been founded by Augustus, came to an end with the suicide of Nero in AD 68. There followed the famous Year of Four Emperors, a brief period of civil war and inst ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

P Elements
''P'' elements are transposable elements that were discovered in ''Drosophila'' as the causative agents of genetic traits called hybrid dysgenesis. The transposon is responsible for the ''P'' trait of the ''P'' element and it is found only in wild flies. They are also found in many other eukaryotes. The ''P'' element encodes for an enzyme known as ''P'' transposase. Unlike laboratory-bred females, wild-type females are thought also to express an inhibitor to ''P'' transposase function, produced by the very same element. This inhibitor reduces the disruption to the genome caused by the movement of ''P'' elements, allowing fertile progeny. Evidence for this comes from crosses of laboratory females (which lack the ''P'' transposase inhibitor) with wild-type males (which have ''P'' elements). In the absence of the inhibitor, the ''P'' elements can proliferate throughout the genome, disrupting many genes and often proving lethal to progeny or rendering them sterile. ''P'' elements a ...

Genetics
Genetics is the study of genes, genetic variation, and heredity in organisms.Hartl D, Jones E (2005) It is an important branch in biology because heredity is vital to organisms' evolution. Gregor Mendel, a Moravian Augustinian friar working in the 19th century in Brno, was the first to study genetics scientifically. Mendel studied "trait inheritance", patterns in the way traits are handed down from parents to offspring over time. He observed that organisms (pea plants) inherit traits by way of discrete "units of inheritance". This term, still used today, is a somewhat ambiguous definition of what is referred to as a gene. Trait inheritance and molecular inheritance mechanisms of genes are still primary principles of genetics in the 21st century, but modern genetics has expanded to study the function and behavior of genes. Gene structure and function, variation, and distribution are studied within the context of the cell, the organism (e.g. dominance), and within the con ...
