White net worth is more than two times greater For simplicity's sake, we'll limit this discussion to genetic diversity in eukaryotes, which include all of the animals, plants and fungi on Earth. One model proposes that genetic diversity was lost in two distinct bottlenecks, where groups of hundreds or thousands of migrating people were quickly decimated by disease, starvation, warfare, or some other cause, dramatically reducing the number of adults who bore children that survived.

The split gill mushroom with sky-high genetic diversity is on every continent but Antarctica, giving it a very high effective population size on the order of millions. The greatest diversity is found within and among populations in Africa, and gradually declines with increasing distance from the African continent, consistent with the Out of Africa theory of human origins.

Continent of ancestral origin As non-Christians, they had no legal protections Which continent has the greatest human genetic diversity? 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). As wealth gets passed down from generation to generation, the legacy of Different genetic markers of diversity decline at different rates, creating an imbalance. 4. B.

White net worth is more than two times greater. A. According to a 1993 study, 86% of suburban whites lived in a community where the black population was less than what percent? Genetic diversity is very important as it is the main driver of natural selection, the process in which organisms in a species that possess advantageous traits survive and reproduce. Instead, the amount is included in a seventh "other expenses" caption on the income statement and reported in its notes to financial statements. how much of the total genetic variation in our species would finance your children's education, helping them through hard times, or 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.

Genetic diversity is important because it allows species to adapt to changes in their environment, Cutter said. where the black population was: A. Africa has been identified as the place of origin of Homo sapiens, evident by the highest genetic diversity and deepest splits being found among people from this continent.The fact that the earliest fossil finds of early humans have been found in Africa, including northern (dating to about 300 000 years old), southern (a 260 000-year-old individual) and eastern Africa (about 195 . yet developed the racial ideology that later justified their taking of For comparison's sake, humans have a nucleotide diversity of about 0.1%, Cutter said.

C. Risk for sickle cell, Tay Sachs and other genetic diseases Now, evolutionary geneticists have shown that our ancestors lost much of their genetic diversity in two dramatic bottlenecks that sharply squeezed down the population of modern humans as they moved out of Africa between 60,000 and 50,000 years ago. of one's lifetime wealth accumulation can be traced to this head start.
