In a population of a certain fish, the gene for fin size has two alleles. The dominant allele leads to large fins, and the recessive allele leads to small fins. Genetic tests on this population show that the frequency of the recessive allele is 0.91. What is the frequency of the dominant allele

0.09

Explanation:

A locus can be defined as a specific genetic location for a particular gene variant (i.e., allele). Diploids organisms (e.g., humans) have two sets of homologous chromosomes, and each pair of homologous chromosomes may have the same alleles or may have 2 different alleles in each locus. Moreover, allele frequency refers to the proportion of one allele with regard to all alleles at the locus in the population. In this case, there are only two alleles for this locus in the population, and the frequency of the recessive allele is equal to 0,91, thereby the frequency of the remaining dominant allele is equal to 0.09 ( 0.91 + 0.09 = 1).
