In mice, black fur (W) is dominant over white fur (w). In an ideal mouse population exhibiting Hardy–Weinberg equilibrium, 167 mice out of 225 have white fur. Calculate the number of mice that are heterozygous dominant for the fur colour gene in the population. Show all work. Express your answer rounded to the nearest whole number:

An allele of the G6PD gene acts in a recessive manner to cause sensitivity to fava beans, resulting in ahemolytic reaction (lysis of red blood cells) afteringestion of the beans. The same allele also confersdominant resistance to malaria. The heterozygote hasan advantage in a region where malaria is prevalent.Will the equilibrium frequency (qe) be the same foran African and a North American country? Whatfactors affect qe?
Color blindness in humans is caused by an X-linked recessive allele. Ten percent of the males of a large andrandomly mating population are color-blind. A representative group of 1000 people from this population migrates to a South Pacific island, where there are already1000 inhabitants and where 30 percent of the males arecolor-blind. Assuming that Hardy–Weinberg equilibrium applies throughout (in the two original populationsbefore the migration and in the mixed population immediately after the migration), what fraction of malesand females can be expected to be color-blind in the generation immediately after the arrival of the migrants?
Different species of crickets have distinct songs, andthey use these songs for mate recognition. Researcherscrossed two species of Hawaiian crickets (Laupala paranigra and L. kohalensis) whose songs are distinguishedby pulse rate (the number of pulses per second; Shaw etal., Molecular Ecology 16, 2007, 2879–2892.) Then, theymapped QTL in the F2 population derived from thiscross. Six autosomal QTL were detected. The mean traitvalues (pulses per second) at the three genotypic classesin the F2 for each QTL are shown in the table below,where P indicates the L. paranigra allele and K indicatesthe L. kohalensis allele.a. Calculate the additive (A) and dominance (D) effectsand the D/A ratio for each of the six QTL.b. Which of these QTL shows the greatest amount ofdominance?c. Which of these has the largest additive effect?d. The mean pulse rate for L. kohalensis is 3.72, and it is0.71 for L. paranigra. Do all six QTL act in the expecteddirection with the L. kohalensis allele conferring a…
Given a population of 10,000 ducks with the following genotypic frequencies : f (BB), black = 0.36; f (bb) white = 0.16 and f (Bb), khaki = 0.48Compute for the gene frequencies of the following : f(p) f(q) 2pq
Suppose that a population is at equilibrium between mutation and selection for a deleterious recessive allele, where s = 0.5 and μ = 10−5. What is the equilibrium frequency of the allele? What is the selection cost?
Hardy-Weinberg Problem; The frequency of the dominant phenotype, brown (B) coat coloris 73% in a population of 1032 mice. The recessive condition is white fur (b). Determine the following and show all work: Frequency of the white genotype in the population Percentage of the population with the genotype BB Number of mice that are heterozygous Frequency of the gominant allels. Number of recessive alleles in the population
Evolution is driven by both nonrandom and random mechanisms. Identify the mechanisms of evolution that are random and comment on how they affect allele frequencies across generations.
In another population, linkage disequilibrium was calculated to be D = 0.15, and the recombination rate between loci was r = 0.10. If there is no selection on this locus, and the population is mating randomly, what would be the predicted value of linkage disequilibrium after five generations? (show all calculations)
The color of the coat of a hypothetical breed of cattle is controlled codominantly by a gene in locus R. A routine inspection of a randomly mating population with 353 animals showed that 13% of them are red , 45% are roan and 42% are white. question: how many animals have the recessive allele?
