WebDec 8, 2024 · Low genetic diversity in the Bi-State, Jackson, and Utah NCs was not observed at the CC level, suggesting low but distinct local genetic diversity at a fine-scale (i.e., low gene flow and genetic drift).

WebMar 5, 2024 · Genetic drift is a random change in allele frequencies that occurs in a small population. When a small number of parents produce just a few offspring, allele frequencies in the offspring may differ, by chance, from allele frequencies in the parents. This is like tossing a coin.
