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?

*This is theq question that goes with the picture* A. 0.0025  B. 0.01  C. 0.95  D. 0.99  E. None of the above

Some individuals in a canine population is susceptible to disease X, which strikes the adults. The susceptibility is later found to be determined by a single locus, with the R allele dominant over the r allele, such that the rr individuals are susceptible to the disease and the others immune. A population genetic survey showed that 1% of the newborns carry the rr genotype. Also, an independent estimation showed that mutation rate converting R to r is 5 × 10-3 per generation. You suspected that the r allele frequency is maintained by mutation- selection balance (MSB). If your hypothesis of MSB is true, then what is the survival rate for the rr adults? (Note: the equilibrium allele frequency ĝ is calculated as ĝ where %3D u is the mutation rate and s is the selection coefficient.) 5% 50% 95% 99% None of the above

If the frequency of a dominant allele “B” in a population is 80%, and assuming genetic equilibrium in this population, what percentage of the offspring in the next generation could be expected to have the heterozygous genotype?

In smurfs, blue tails and red tails are codominant to white tails (this is similar to blood type in humans). In a population of 200 smurfs, 6 have white tails, 93 have blue tails, 51 have red tails, and 50 have purple tails. Papa smurf has learned that the frequency of the blue tail allele is 0.53. Is this population in Hardy-Weinberg Equilibrium? Be sure to do a Chi-square test and show your work.

Imagine you have a VERY large garden consisting of thousands of red-flowered individuals (recessive homozygotes rr) and just a few dozen white-flowered plants (genotypes either RR or Rr) of the same species. The garden is isolated from all other flower populations. What do you think will happen to the frequency of the white-flowered plants in your garden from year to year, assuming that the two phenotypes survive and reproduce equally well, that flower color is inherited as a dominant trait, and that pollinating insects make no distinction in flower color? Why?

Average human height has changed over the past few centuries. The current generation's average height is 168 centimeters (i.e. 5 foot 10 in). The selection coefficient for height is ß = 0.08, phenotypic variation is Vp = 1.5, and heritability is h² = 0.45. = a. What is the response to selection (R) for height? b. What is the average height expected to be for the next generation? c. Would you say this is strong or weak selection?

In mice, albinism (g) is recessive to grey coat colour (G). The fur colour in mice is a single gene trait controlled by two alleles.In an ideal mouse population exhibiting Hardy–Weinberg equilibrium, a grey mouse mated with an albino mouse. Over the course of several months, 55 pups were born.If the grey allele has a frequency of 0.618, which of the following rows identifies the number of the grey and albino alleles in the population of 55 pups? Group of answer choices Grey Allele Albino Allele 34 21 Grey Allele Albino Allele 68 42 Grey Allele Albino Allele 42 68 Grey Allele Albino Allele 21 34

If there are 12 rock pocket mice with dark fur and 4 with light-colored fur in a population, what is the value of q? Remember that light-colored fur is recessive. If the frequency of p in a population is 60% (0.6), what is the frequency of q? In a population of 1000 rock pocket mice, 360 have dark-colored fur. The others have light-colored fur. If the population is in Hardy-Weinberg equilibrium, what percentage of mice in the population are homozygous dominant dark-colored mice?
