A population has the following gametic frequencies attwo loci: AB = 0.4, Ab = 0.1, aB = 0.1, and ab = 0.4. Ifthe population is allowed to mate at random until linkage equilibrium is achieved, what will be the expectedfrequency of individuals that are heterozygous at bothloci?

The sd gene causes a lethal disease of infancy in humanswhen homozygous. One in 100,000 newborns die eachyear of this disease. The mutation rate from Sd to sd is2 × 10−4. What must the fitness of the heterozygote be toexplain the observed gene frequency in view of the mutation rate? Assign a relative fitness of 1.0 to Sd /Sd homozygotes. Assume that the population is at equilibriumwith respect to the frequency of sd.

Color in a species of minnow is determined by a single locus with two alleles: D and d. DD individuals are dark, Dd are intermediate, and dd are pale. In a population that is in Hardy–Weinberg equilibrium, we count 74 pale minnows out of 202. How many minnows do you expect to be dark?

the aggresive behavior in cats is controlled by a completely dominant gene locus A. There are 46 docile cats in subdivision with a population of 158. Question: Determine if how many animals are heterozygous and how many animals have the dominant allele? provide solution

Hartnup disease is an autosomal recessive disorder of intestinal and renal transport of amino acids. The frequency of affected newborn infants is about 1 in 14,000. Assuming random mating, what is the frequency of heterozygotes? Provide summation

In the Ireland, 9% of the population is red haired.  Assuming mating is random, what is the frequency of heterozygotes in Ireland?

During a blood donation campain at the University of Montana, allele frequencies determinnh abo blood groups were 0.60 for i, 0.2 for IA and 0.2 IB. Assuming random mating, what is the expected frequency of blood type B?

Briefly describe what can be expected during consanquineous matings as they disproportionally contribute to the incidence of rare autosomal recessive conditions.  What is a genetic drift and what is the effect of new mutations and natural selection for populations?

Consider a population that is in Hardy-Weinberg equilibrium at a locus with two alleles, A and a, at frequencies of p and q, respectively. Assuming the population remains in Hardy-Weinberg equilibrium, what is the expected frequency of Aa heterozygotes after 100 generations? 0.5 p2 2pq O1

The frequency of a recessive allele in a population is 40%. What variable in the Hardy Weinberg equations does the 40% refer to? Why?
