In a population at Hardy-Weinberg equilibrium, if the frequency of the g allele is 0.6, what percentage of all alleles in the population are g?
A

D
16%
Verified step by step guidance1
Understand that the frequency of an allele in a population is the proportion of all alleles at that gene locus that are of that specific type. Here, the frequency of the g allele is given as 0.6.
Recall that allele frequencies in a population must add up to 1. If the frequency of the g allele is 0.6, then the frequency of the other allele(s) is 1 - 0.6 = 0.4.
Since the question asks for the percentage of all alleles that are g, convert the allele frequency from a decimal to a percentage by multiplying by 100.
Use the formula: $\text{Percentage of g alleles} = \text{frequency of g} \times 100$.
Calculate the percentage to find the proportion of g alleles in the population.
