a lizard population has two alleles
A: –
Concept:
At a two-allele gene locus, let p be the frequency of allele A and q the frequency of allele a (p + q = 1).
Under Hardy-Weinberg equilibrium, genotype frequencies are AA: p^2, Aa: 2pq, aa: q^2. – One clear example: Locus for color with alleles B (blue) and b (green).
If p = 0.6 (B) and q =
0.4 (b), expected genotypes are BB
0.36, Bb
0.48, bb
0.
16. – Brief example: If p = 0.7 and q =
0.3, genotype frequencies are AA
0.49, Aa
0.42, aa
0.
