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) More than 73% of the populations would have only one allele present.
B) About 73% of the populations would have only one allele for the bristle morphology gene.
C) Less than 73% of the populations would have only one allele present.
D) All of the populations would have only one allele present.

Allowing more individuals to breed each generation will increase genetic variation within the populations, making it less likely for a single allele to become fixed (present in all individuals). Therefore, we would expect less than 73% of the populations to have only one allele present.
