In a species of fish, fin shape is controlled by a single gene that has only two alleles. in a generation of 185 fish, the frequency of the recessive allele is 0.25. after six generations, the recessive allele frequency in a population of 230 fish is 0.43. which of the following does this most likely indicate about the dominant and recessive alleles? the dominant allele is more advantageous than the recessive allele because it produces larger populations. the dominant allele will disappear entirely as the recessive allele increases in frequency. the recessive allele is easier to transmit than the dominant allele during reproduction. the recessive allele produces a phenotype that is better able to survive and reproduce than the dominant phenotype.

The genetic inheritance of blue eye color in humans behaves a lot like a simple recessive trait, though in truth, eye color is actually controlled by multiple alleles. as a simple model, assume that eye color is controlled by a single gene, where the allele, b, for brown eyes is completely dominant over the allele, b, for blue eyes. given that a population's dominant allele frequency, p, is twice the recessive allele frequency, q, what percent of the population will have brown eyes but will still carry the blue eye allele? a) 44.4 percent b) 11.1 percent c) 22.2 percent d) 88.8 percent
