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.
