In Kerr and Wright's experiment with 96 fruit-fly populations,only 4 males and 4 females bred in each generation.After 16 generations,73% of their populations had only one allele present for the bristle morphology gene.Which of the following would you expect to occur if they allowed 10 males and 10 females to breed each in generation?
A)About 73% of the populations would have only one allele for the bristle morphology gene.
B)More than 73% of the populations would have only one allele present.
C)Less than 73% of the populations would have only one allele present.
D)All of the populations would have only one allele present.

The small number of breeding individuals in each generation, 4 males and 4 females, likely contributed to the high percentage (73%) of populations with only one allele for the bristle morphology gene. Allowing 10 males and 10 females to breed would increase genetic diversity, making it less likely for a single allele to become fixed in the population. Therefore, we would expect less than 73% of populations to have only one allele present.
