Question

In a population of birds, the allele for wide beaks (B) is dominant to the allele for narrow beaks (b). If 50% the population is heterozygous and 25% is homozygous for narrow beaks, what is the frequency of the allele for wide beaks?

Answer 1

An allele frequency is calculated by dividing the number of times the allele of interest is observed in a population by the total number of copies of all the alleles at that particular genetic locus in the population. Allele frequencies can be represented as a decimal, a percentage, or a fraction.
