Summary Introduction

To determine:

The expected frequencies of genotype AA, Aa, and aa in the population.

Introduction:

According to the Hardy-Weinberg equilibrium, the allelic and genotypic frequencies of the population will remain the same from one generation to another if there are no external evolutionary forces.

If a population is in Hardy-Weinberg equilibrium for the multiple alleles A+, A and a, whose frequencies are p= 0.60 for A+, q= 0.20 for A, and r = 0.20 for a, what percentage of the population is expected to be heterozygous?
In a population of 200 people, an allele F has a frequency of 84%. What is the frequency of allele f? Using the Hardy-Weinberg equation, estimate the numbers of homozygous dominant, heterozygous, and homozygous recessive genotypes. (Remember that the formula is: p2 + 2pq + q2 = 1, where p represents the dominant allele and q represents the recessive allele.) *Be sure to account for all 200 people in the population.
Consider a population in which the D locus has two alleles, D and d, with f(D) = 0.6 and f(d) = 0.4. What are the genotypic frequencies expected under Hardy-Weinberg equilibrium?
