Question

You are not sure if a population of 1000 ladybugs is in Hardy-Weinberg equilibrium or not. At a locus with two alleles, B and b, the frequency of dominant homozygotes (BB) is 0.4 and the frequency of recessive homozygotes (bb) is 0.4. 1. What is the frequency of the B allele? [ Select ] ["0.16", "0.32", "0.50", "0.63", "0.7"] . 2. Is this population in Hardy-Weinberg equilibrium or not? Yes or No?

Step 1

The frequency of bb is given as 0.4. In Hardy-Weinberg equilibrium, the frequency of bb (q²) is equal to the frequency of the recessive homozygotes. Therefore, we can find q (the frequency of allele b) by taking the square root of 0.4. \[ q = \sqrt{0.4} \approx Show more…
