In populations of finite size, sampling of gametes from the gene pool can cause evolution.

Incorporating Genetic Drift. In populations of finite size, sampling of gametes from the gene pool can cause evolution. Probability of Maintaining the Same Initial Allele Frequency. The Ultimate Fate of Random Genetic Drift. The Effects of Drift are More Pronounced in Smaller Populations.

RATES OF NUCLEOTIDE SUBSTITUTION

RATES OF NUCLEOTIDE SUBSTITUTION. rate = # substitutions per site per unit time (year or generation). Ancestral sequence. Sequence 2. Sequence 1. If r = rate K = # sub between 2 homologous sequences T = time of divergence. r = K / 2T. Then.
