The APsolute Recap: Biology Edition - Population Genetics
Episode 41 recAPs the random side of evolution. Melanie begins with a vocab review - allele, gene, heterozygous (1:00). This episode is about population genetics because populations are the level of ecological organization where evolution occurs (1:40). Mutations are the primary source of genetic variation, providing new phenotypes on which natural selection can act (2:40). It's important to distinguish between gene flow and genetic drift (3:24). Two types of genetic drift are the bottleneck effect (4:10) and the founder effect (4:50).
The Question of the Day asks (6:30) “What do the p and q represent in Hardy-Weinberg equilibrium?
