Harris 1966 measured the number of genotypes at the alkalinephosphate locus in the English population. There are three alleles,designated F, I, and S (for fast, intermediate,and slow mobility inan electropheritc apparatus)

1. What are the observed frequencies of the six genotypes?

2. What are the observed allele frequencies for the threealleles?

3. What are the Hardy-Weinberg equilibrium frequencies of thegenotypes?

4. What are the Hardy-Weinberg equilibrium frequencies of thealleles?

5. What is the total observed heterozygosity (i.e. frequency ofall heterozygotes)?

6. What is the total heterozygosity at Hardy-Weinbergequilibrium?

7. Calculate F from the observed and equilibriumheterozygosities. Does this suggest to you any departures fromHardy-Weinber conditions, and, if so, what kind of departure?

1.) What are the Hardy-Weinberg equilibrium frequencies of thegenotypes?

Can someone please help me with the following questions. Pleaseprovide an answer/explanation especially for the first three.

?. Suppose a population of flour beetles has 1,000 individuals.Normally the beetles are red; however, this population ispolymorphic for a mutant autosomal body color, black, designated bybb. Red is dominant to black, so BB and Bb genotypes are red.Assume the population is at Hardy–Weinberg equilibrium, with equalfrequencies of the two alleles. What would be the allelefrequencies if a population bottleneck occurred and only fourindividuals survived: one female red heterozygote and three blackmales? A) 0.125 red; 0.875 black B)0.875 red; 0.125 black C) 0.25 red;0.75 black D) 0.75 red; 0.25 black E) 0.5 red;0.5 black

?. What would be the expected frequencies of the red and blackphenotypes in the original population of beetles? A) 0.5 red; 0.5black B) 0.75 red; 0.25 black C) 0.25 red; 0.75black D) All red E) Insufficient information is given to answer thequestion.

?. Given the original population data and a Hardy-Weinbergequilibrium, what are the frequencies of the homozygous dominant,heterozygous, and homozygous recessive (in that order) after 100generations, assuming that no selection or other evolutionaryprocesses are operating?

A) compare pieces ofDNA coding for a structural protein that is present in both speciesB) studying the many nucleotide sites in both species and taking anaverage differences between DNA and RNA C) comparing pieces of DNAfor a functional enzyme that is present in both species D)comparing the DNA differences between two species in non-codingregions E) Comparing fitness levels
