A gene in a population of sexually reproducing organisms with the following genotype frequencies is at Hardy-Weinberg Equilibrium: BB 100, Bb 800, bb 100
A) true B)false C) can not be determined
Which of the following evolutionary forces would be the best explanation for the genotype frequencies in the population in the above question?
A) genetic drift B) there are no evolutionary forces acting on this gene population C)assortive mating D) Overdominance E)Directional selection
If a population is at Hardy-Weinberg equilibrium, which of the following allele frequencies would yield the smallest number of heterozygotes? A)
A=0.25, B=0.75 B) A=0.75, B=0.25
C)A=0.50, B=0.50
D)A=0.10, B=0.90
Fixation occurs when one allele becomes the only allele for a gene in a population, meaning that all other alleles for that gene have been lost. True or false

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).
