1. D3: Thursday, 12/19 Tahlia collected data for the bluejay population this summer. She calculated the allele frequencies for a certain gene (toe length). Freq A = 0.6, Freq a = 0.4. She plans to sample the population again after three generations. If the allele frequencies HAVE NOT CHANGED at that time (0.6, 0.4), is the population evolving for that gene (toe length)?

2. Key Concepts: Genetic variability: genetic drift, gene flow, non- random mating, mutations, natural selection Genetic equilibrium: Hardy-Weinberg principle Speciation Patterns of evolution: gradualism, punctuated equilibrium, adaptive radiation/divergent evolution, convergent evolution (analogous structures), coevolution, extinction (gradual, mass)
