14A. Suppose a population of flour beetles has 10,000 individuals. There are two alleles possible for the gene that determines body color: red (B), and black (b). BB and Bb beetles are red, while bb individuals are black. Assume the population is at HardyâWeinberg equilibrium, with equal frequencies of the two alleles.
What would be the expected frequency of red beetles?
14B. What would be the expected frequency of black beetles in the population as described in A?
14C. Assuming that Hardy-Weinberg equilibrium remains in effect, what would be the expected frequencies of BB, Bb, and bb individuals after 100 generations?
| BB = 0.5, bb = 0.5 |
| Bb = 0.75 bb = 0.25 |
| BB = 0.75 bb = 0.25 |
| BB = 0.25, Bb = 0.5, bb = 0.25 |
| The answer cannot be determined. |
14D. What would be the expected red (B) allele frequency if 10,000 black individuals migrated into the population?
14E. What would be the expected black (b) allele frequency after the migration described in part D?
14F. Violation of what two Hardy-Weinberg assumptions could return the population to the original allele frequencies (described in A)? Briefly explain how each violation would return the population to the original allele frequencies in 1-2 sentences (each).
