Two chromosome inversions are commonly found in populations ofDrosophila pseudoobscura: Standard (ST) and Arrowhead (AR). Whenthe flies are treated with the insecticide DDT, the genotypes for theseinversions exhibit overdominance, with the following fitnesses:Genotype FitnessST/ST 0.47ST/AR 1AR/AR 0.62What will the frequencies of ST and AR be after equilibrium has beenreached?

A population sample of 300 individuals is studied for the electrophoretic mobility of an enzyme that varies according to the genotype determined by 2 alleles, E and T of a single gene. The results are 7 individuals with genotype EE, 106 with genotype ET, and 187 with genotype TT. What are the allele frequencies of E and T, and what are the expected numbers of the 3 genotypes if random mating is assumed?
You have collected and determined genotypes of 200 individuals from a population of thr fruit fly, Drosophila pseudoobscura. Your sequencing study revealed 20 individuals with genotype AA, 70 individuals with genotype Aa and 110 individuals with genotype aa. i) what are your theoretical expectations for the number of individuals with each genotype if the population is in Hardy-Weinberg equilibrium. ii) Based on the genotype counts observed, is there evidence that this population of fruit flies deviates from your theoretical expectations under Hardy-Weinberg equilibrium?
In a randomly mating laboratory population of Drosophila, 4 percent of the flies have black bodies (encodedby the autosomal recessive b), and 96 percent havebrown bodies (the wild type, encoded by B). If this population is assumed to be in Hardy–Weinberg equilibrium, what are the allele frequencies of B and b and thegenotypic frequencies of B/B and B/b?
A wild-type fruit fly (heterozygous for gray body color andnormal wings) is mated with a black fly with vestigial wings.The offspring have the following phenotypic distribution: wildtype, 778; black vestigial, 785; black normal, 158; gray vestigial,162. What is the recombination frequency between these genesfor body color and wing size? Is this consistent with the resultsof the experiment in Figure 15.9?
Using the HardyWeinberg Law in Human Genetics In a given population, the frequencies of the four phenotypic classes of the ABO blood groups are found to be A = 0.33, B = 0.33, AB = 0.18, and i = 0.16. What is the frequency of the i allele?
DDT is a deadly insecticide that was used to kill mosquitos in malaria endemic areas. Mosquitos with the DD genotype are less affected by DDT, producing 25 offspring on average. In contrast, mosquitos with the Dd genotype produce 15 offspring and those with the dd genotype 10 offspring on average. Assume the initial f(D)=p=0.560 and the mean fitness (w bar)=0.687, what will the relative genotypic frequency of the heterozygote (Dd) be after selection?
The mean and standard deviation of plant height from two rice plants (P1 and P2) and their progeny (F1 and F2) and a backcross generation (P1 x F1) are shown below. Complete the table by calculating the variances and coefficient of variation for each population and answer the questionswhich follow (See image) 1. Explain the possible reasons for the observed differences in the sample means. Account forthe differences in the sample means of P1 and P2. Similarly, account for the differences in thesample means of the F1 and F2. Compare the difference in the parental generations with thatin the filial generations.2. Interpret the CV values from each population.3. Compare the sample variances of P1 and P2. Account for any differences. Similarly, comparethe sample variances of the F1 and F2 generations, and account for any differences. Give thepossible causes of variation in each generation.4. Calculate the broad-sense heritability of plant height in this species. Interpret your results.
In corn, kernel color is governed by a dominant allele for white color (W) and by a recessive allele for yellow (w). A random sample of 152 kernels from a population that is in Hardy- Weinberg equilibrium reveals that 35 kernels are yellow and 117 kernels are white. What is the frequency of individuals with the homozygous dominant genotype?
Two alleles have been found at the X-linked phosphoglucomutase gene (Pgm) in a Drosophila persimilispopulation in California. The frequency of the PgmAallele is 0.25, while the frequency of the PgmBalleleis 0.75. Assuming the population is at Hardy-Weinbergequilibrium, what are the expected genotype frequencies in males and females?

In a certain population of frogs, 120 are green, 60 are brownish-green, and 20 are brown. The allele for brown is denoted GB, and the allele for green is designated GG. These two alleles are incompletely dominant to each other. What is the frequency of genotype GGGG in this population?
