Question

For gene B in a population of moths, the following genotypes were found in the following frequencies. 45 BB:347 Bb:8bb

What is the allele frequency of the B allele?

Answer 1

Allele frequency is a measure of the relative frequency of an allele on a genetic locus in a population. Allele frequency is determined by counting how many times an allele appear in the population divided by total number of copies of the gene.

Frequency of allele A = number of copies of allele A in a population/total number of copies of gene in a population

For gene B in a population of moths, the following genotypes were found in the following frequencies. 45 BB: 347 Bb: 8 bb.
