In a population of 1,000 individuals, a particular gene has two alleles: "A" and "a." The allele frequency for "A" is 0.6, and for "a," it is 0.4. According to the Hardy-Weinberg equilibrium, what would be the expected number of heterozygous individuals (Aa) in this population? 360 480 600 720

Solution

The Hardy-Weinberg equilibrium is a principle stating that the genetic variation in a population will remain constant from one generation to the next in the absence of disturbing factors.

The formula for Hardy-Weinberg equilibrium is p^2 + 2pq + q^2 = 1, where:

  • p^2 represents the frequency of homozygous dominant individuals (AA)
  • 2pq represents the frequency of heterozygous individuals (Aa)
  • q^2 represents the frequency of homozygous recessive individuals (aa)

In this case, we are given that p (the frequency of allele A) is 0.6 and q (the frequency of allele a) is 0.4. We are asked to find the expected number of heterozygous individuals (Aa), which is represented by 2pq.

So, we calculate 2pq as follows:

2pq = 2 * 0.6 * 0.4 = 0.48

This is the proportion of heterozygous individuals in the population. To find the actual number of individuals, we multiply this proportion by the total population size:

0.48 * 1000 = 480

So, the expected number of heterozygous individuals (Aa) in this population is 480.
