Genetic studies in Africa have been severely limited, largely owing to the logistics involved in sample collection and storage, travel to remote villages, and gaining ethics approval in each country. Hanchard and the research team were surprised by the amount of undocumented information they found, leading to two key takeaways from the study. These advantageous traits (and also disadvantageous ones) arise from different variations of genes: these are called alleles. The Civil Rights Act made racial discrimination in public places illegal. In contrast, if the species has genetic variation within the gene, perhaps one version of it will allow an individual to resist the disease, saving the species. Chimpanzees

Humans outside of Africa are missing many genetic variants found only in Africans and, indeed, the farther a traditional group lives from Africa, the less diversity it has in its genes and morphological traits, including skull shape (Science, 6 January 1995, p. 35). But a genetic analysis of its native people has revealed something even more extraordinary - the local inhabitants are some of the most genetically diverse people in the world. What's the most genetically diverse species? Introduction. Key factors that influence a species' genetic diversity are its mutation rate, population size and population stability, Cutter said. separate all members of one race from all members of another race? than any other group. In the most comprehensive study of Africangenetic diversity to date, a team of international scientists, led by Dr Sarah Tishkoff from the University of Pennsylvania in Philadelphia, US, has revealed Africa to be the most genetically diverse continent on Earth. 1862 Homestead Act All modern humans originated from Africa, and we spent most of our evolution as a species together there. 85%, or almost all human variation, can be found within any single local

ScienceDaily. In a single reasonably homo-geneous population, genetic diversity of biparentally transmitted DNA can be assessed efciently by counting hetero-zygotes for all variants. "It takes time for mutations to build up in a population as it grows to create genetic diversity.". One of the researchers, Muntaser Ibrahim, from the University of Khartoum, Sudan, said 'This is a spectacular insight into the history of African populations and therefore the history of mankind'. When you purchase through links on our site, we may earn an affiliate commission. With the recent publication of a large data set of 763 microsatellite markers--short stretches of DNA that are repeated in the genome--from 53 populations in the Human Genome Diversity Project, evolutionary geneticists William Amos and Joe Hoffman of the University of Cambridge in the United Kingdom had enough genomic data to test both models. A. Europe
Essentially, genetic diversity is a measure of how often two bits of DNA from the same genomic location differ from one another within a population, Asher Cutter, a professor in the Department of Ecology and Evolutionary Biology at the University of Toronto, told Live Science. E. Capt. Also, humans have always moved,
If a population goes through a bottleneck, or an event that wipes out much of a population, spends some time as a smaller group and then rebounds, the genetic diversity of the resulting population will be lower, he added.
