8) In a population of chimps, a gene that controls the presence or absence of an extra digit on forelimbs is in Hardy-Weinberg equilibrium. This gene has two alleles (D1 and D2), and 40% of the gametes in the chimp population carry the D1 allele. Given this information, what is the percentage of chimps that carry both the D1 and D2 alleles? a.16% b.48% c.60% d.40% e.36%
There is no effect of selection on the Hardy Weinberg Equilibrium. O A. True B. False.
Consider a hypothetical beetle population, in which beetle colour variesalong a spectrum from light to dark green. When introduced to anenvironment characterized by light green moss and dark green shrubs,both light and dark green beetles have higher fitness than medium greenbeetles. Which of the following terms best describes this situation? Select one:O a. Stabilizing selectionO b. Directional selectionO c. Disruptive selectionO d. Sexual selection
If the X3 allele is undergoing positive selection, what will be the likely end result? A There will be no individuals that are X3X3 B All individuals will be X1X3 or X2X3 because of the heterozygote advantage. C The variance of the trait will stay the same, but the mean value will increase. D The frequency of X3 will increase and it could potentially become fixed in the population. e The allele frequency of X1 and X2 will stay the same, but the allele frequency of X3 will increase.
Many species of birds choose their mates based on how brightly colored they are. If feather color is heritable, how would this violate the assumptions required for a population to be in Hardy-Weinberg equillibrium? HW equilibrium would cause mutations in such a species. A. This is a founder effect В. This is a bottleneck effect C. OD. Mating is non-random. Alleles for brightly colored phenotypes might become more common in the species and allele frequency would change.

Consider a gene with two alleles, L and M, that exhibit complete dominance. The table below provides the relative fitnesses of the three genotypes in two populations. LL LM MM Population 1 0.8 0.3 0.3 Population 2 0.9 1.0 1.0 a. Which allele is dominant, and how do you know? b. Which allele will increase (in each population), and how do you know? c. In which population will the change in allele frequencies occur more quickly, and how do you know?
Consider a gene with two alleles, G and g, and heterozygote superiority. Which statement about the fitness of each genotype is correct? A. The fitnesses of the three genotypes would be the same B. The fitness of gg would be greater than that of wither Gg or GG C. There is not enough information to tell D. The fitness of GG would be greater than that of either Gg or gg E. The fitness of Gg would be greater than that of wither gg or GG
If the frequency of allele 1 is 0.8 and the frequency of allele 2 is 0.2 what is the expected frequency of heterozygotes under Hardy Weinberg? Group of answer choices A. 0.32 B. 0.8 C. 0.2 D. 0.16
22. The graph shows the distribution of a trait in an animal population. mean Range of variable If the species were to undergo stabilizing selection in which extreme phenotypes were selected against, how would the graph be expected to change?
