In a random mating population of 100000 individuals, the frequency of the recessive allele is 0.4 , how many individuals will have the dominant phenotype?

To determine how many individuals will have the dominant phenotype in a random mating population, we first need to calculate the frequency of the dominant allele.

Since the frequency of the recessive allele is given as 0.4, we can calculate the frequency of the dominant allele by subtracting the frequency of the recessive allele from 1.

Frequency of the dominant allele = 1 - Frequency of the recessive allele = 1 - 0.4 = 0.6

Now, we can calculate the number of individuals with the dominant phenotype by multiplying the frequency of the dominant allele by the total population size.

Number of individuals with dominant phenotype = Frequency of the dominant allele * Total population size
Number of individuals with dominant phenotype = 0.6 * 100,000 = 60,000

Therefore, in a random mating population of 100,000 individuals with a frequency of the recessive allele at 0.4, there will be 60,000 individuals with the dominant phenotype.
