In a species of insect, wing length is determined by a single gene, for which there are only two alleles. in a population of 150 insects, the frequency of the recessive trait is 0.05, after four generations, the recessive allele frequency is 0.31in a population of 125 insects. which of the following does this most likely suggest about the recessive allele? a. after about 20 generations, the recessive allele will be the only one that exist for the gene. b. it is not advantageous to the insects because it results in an overall decrease in the population c. it results in a phenotype that makes the insect better fit to survive in its environment d. because it is still not a dominant allele, it does not have a significant impact on the survival of the species.
