In Kerr and Wright's experiment with 96 fruit-fly populations, only 4 males and 4 females bred in each generation. After 16 gene

rations, 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?
1 About 73% of the populations would have only one allele for the bristle morphology gene.
2.Less than 73% of the populations would have only one allele present.
3.More than 73% of the populations would have only one allele present.
4.All of the populations would have only one allele present.

Less than 73% of the populations would have only a single allele present. In the experiment conducted by Kerr and Wright, the alleles examined did not influence the fitness of the flies in the laboratory setting. Thus, they could confidently conclude that variations in the frequencies of the normal and forked phenotypes were not a result of natural selection. Expanding the breeding population would be unlikely to change the experiment's results.
