selection, drift, gene flow, and common ancestry

WORKED MODELWORKED SOURCE

Allele frequency after selection

A beetle population begins with 500 green and 500 brown adults. After predation, 400 green and 200 brown survive and reproduce equally.

  1. Survival differs by phenotype.
  2. Green survival is 80%; brown survival is 40%.
  3. Selection changes representation among breeders.
