Description of genetic drift
WebDec 8, 2024 · Genetic variation is strongly influenced by the multi-generational shifting balance among new alleles arriving through mutation and immigration and the loss of alleles to genetic drift (Row et al., 2016; Wright, 1931 ). Thus, we expect patterns of genetic variation to largely mirror long-term patterns in population abundance.
