With directional selection against the A₁ allele we can predict that it will either become rare or go extinct (frequency = 0). Which result occurs depends on the dominance relationships of the alleles. In which situation would the A₁ allele be LEAST likely to go extinct? Think about what kind of dominance exists in a lot of disease- causing alleles. The A, allele is dominant to the A, allele. The alleles are incompletely dominant (or co-dominant). The A, allele is dominant to the A, allele.

When alleles at a locus act in a semidominant fashionon fitness, the relative fitness of the heterozygote ismidway between the two homozygous classes. For example, genotypes with semidominance at the A locusmight have these relative fitnesses: wA/A = 1.0, wA/a =0.9, and wa/a = 0.8.a. Change one of these fitness values so that a /a becomes a deleterious recessive allele.b. Change one of these fitness values so that A/A becomes a favored dominant allele.
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?
In human population X, consider the simple Mendelian trait for freckles. F is the dominant allele and f is the recessive allele. Individuals who are homozygous dominant (FF) or heterozygous (Ff) for the trait express freckles. Individuals who are homozygous recessive (ff) for the trait do not express freckles. In this population, 30% (0.3) of the alleles are recessive (f) and 70% (0.7) are dominant (F). Q1. Use the Hardy-Weinberg equation to determine the genotype frequencies we should expect in the next generation. Be sure to show your work. Q2. You have collected data on the observed genotype frequencies of the next generation. They are: 60% FF, 30% Ff, and 10% ff. Based on these observations and your expectations, is this trait currently evolving in this population? Why or why not? Show your work.
Imagine a locus with two alleles. Mutation at this locus changes one allele to the other (i.e. it does not create a new allele). If the rate of mutation from allele 1 to allele 2 is 0.00005 and the rate of mutation from allele 2 to allele 1 is 0.01, what is the equilibrium frequency of allele 2 (Give your answer to 5 decimal places)?
In a large, randomly mating population, the frequency of the allele (s)for sickle-cell hemoglobin is 0.028. The results of studies have shownthat people with the following genotypes at the beta-chain locus producethe following average numbers of offspring:Genotype Average numberof offspring producedSS 5Ss 6ss 0a. What will the frequency of the sickle-cell allele (s) be in the nextgeneration?b. What will the frequency of the sickle-cell allele be at equilibrium?
Sickle Cell Anemia is an example of "balancing selection" in which natural selection works against the extremes of a trait and favors the intermediate phenotype (e.g. the heterozygous "carriers" of the sickle cell trait) True or false?
In a particular population of mice, certain individualsdisplay a phenotype called short tail, which is inherited as a dominant trait. Some individuals display arecessive trait called dilute, which affects coat color.Which of these traits would be easier to eliminatefrom the population by selective breeding? Why?
Some people can taste the bitter compound phenylthiocarbamide while others cannot. This trait isgoverned by a single autosomal gene; the allele fortasting is completely dominant with respect to the allele for nontasting. Among 1707 Hawaiians tested forthe ability to taste, 1326 tasters were found. Assumingthat the population is at Hardy-Weinberg equilibriumfor this gene and that mating is purely random:a. What are the allele frequencies for the tasting alleleT [= (p)] and for the nontasting allele t [= (q)]?b. What are the genotype frequencies in the population?c. Of all the matings in the population, what proportion will be between two nontasters?d. Of all the matings in the population, what proportion will be between a taster and a nontaster?e. Of all the matings in the population, what proportion will be between a taster male and a nontasterfemale?f. What proportion of all of the progeny produced byall matings between a taster male and a nontasterfemale will be nontasters?g. Of all…
When an allele is dominant, why does it not alwaysincrease in frequency to produce the phenotypeproportion of 3:1 (3/4 dominant : 1/4 recessiveindividuals) in a population?
The MN blood group is of interest to population geneticists because (a) people with genotype MN cannot receive blood transfusions from either MM or NN people (b) the MM, MN, and NN genotype frequencies can be observed directly and compared with calculated expected frequencies (c) the M allele is dominant to the N allele (d) people with the MN genotype exhibit frequency-dependent selection (e) people with the MN genotype exhibit heterozygote advantage
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?
How Can We Measure Allele Frequencies in Populations? The MN blood group is a single-gene, two-allele system in which each allele is codominant. Why are such codominant alleles ideal for studies of allele frequencies in a population?
