Chapter 21.2, Problem 1CC

A population has 700 individuals, 85 of genotype AA, 320 of genotype Aa, and 295 of genotype aa. What are the frequencies of alleles A and a?

What is the frequency of the heterozygous genotype if the homozygous genotype frequencies are 0.1385 (BB) and 0.5897 (bb)?
An F2 ratio of 12:3:1 is most characteristic of a genetic interaction involving? 1) two gene loci with two alleles per locus 2) three gene loci with two alleles per each gene 3) two alleles of the same gene 4) multiple alleles of one gene
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.
