A population is solely comprised of 120 A2A2 individuals.  18 A1A1 individuals migrate in and contribute to the mating pool.  What is the frequency of A1A2 individuals in the offspring?  Answer to 2 decimal places.  Hint:  Use the Gene Flow table!



Expert Answer

Step 1

According to the Hardy-Weinberg equilibrium, the frequencies of the alleles and genotypes in a population remain the same for various generations. Generally, allele and genotype frequencies change over time due to evolution, so a population that follows Hardy-Weinberg equilibrium does not evolve. The assumptions made for Hardy-Weinberg equilibrium are no mutation, no gene flow, no mating, and no natural selection.

Step 2

According to the Hardy-Weinberg equation-
