Problem:
A large population of hawkmoths lives in a valley in Canada. Genetic tests reveal the following frequencies of alleles for wing color: Freqency Allele 0.4 C 0.5 ct 0.1 c- Phenotype Blacked wing (dominant to ct and c-) Tan wing (dominant to c-) White wing (recessive to both other alleles)
Required:
Question 1: If moths mate randomly, what would be the frequencies of moths with black, tan, and white wings be in the next generation?
Question 2: A small group of moths flies to neighboring Montana and establishes a new population. After several generations, there is a large randomly-mating population of hawkmoths. Observations of the Montana moths reveal the following: Phenotype and Frequency Black wings 0.8 Tan wings 0.0 White wings 0.2
Question 3: What are the allele frequencies for C, ct, and c-? What evolutionary explanation can you deduce from the change in allele frequency in the Montana population as compared with the original Canadian population (be specific)?
