Statistical Analysis of Genetic Variation Within and Among Human Populations-Including

Statistical analysis of genetic variation within and among human populations-including those we identify as different races-reveals:

A) more genetic variation between groups than we see within groups.
B) more genetic variation within groups than we see between groups.
C) no clear pattern of genetic variation-in some regions, we would see more variation within than among groups, and in some regions we would see the opposite.
D) a correlation between the amount of genetic variation between groups and the length of time the groups have been isolated from one another.
E) None of the answer options is correct.
