QUESTION 1: A large population of hawkmoths lives in a valley in Canada. Genetic tests reveal the following frequencies of alleles for wing colour:

a) If moths continue to mate randomly, what would be the frequencies of moths with black, tan, and white wings in the next generation?

As per hardy Weinberg equilibrium,

Frequency of black wings = (0.5)2 + 2(0.5) (0.4) +2(0.5) (0.1) = 0.75

Frequency of tan wings = (0.4)2 + 2(0.4) (0.1) = 0.24

Frequency of white wings = (0.1)2 = 0.01

b) A small group of the moths flies to neighbouring Montana and starts a new population. After several generations, there is a large randomly-mating population of hawkmoths. Observations of the Montana moths reveal the following:

What are the allele frequencies for C, ct, and cw?

Since the tan wings is zero, then the frequencies of C, ct, and cw are 0.5, 0 and 0.5 respectively (C and Cw ha....
