If gene A/a is not in Hardy-Weinberg equilibrium due to natural selection such that individuals with the genotype AA have a fitness value of 1.0, heterozygotes have only slightly reduced fitness at 0.9, and individuals with the genotype aa have a fitness value of 0.6, what kind of change in allele frequency would you expect to see over time assuming you start with equal frequencies of the 2 alleles?
How does population size affect the likelihood of changes in allele frequencies by chance alone? Can significant changes in allele frequencies (that is, evolution) occur as a result of genetic drift?
Why is population level genetic variation important for evolution and what causes genetic variation ? How do we detect if evolution is occurring ?

- How Can We Measure Allele Frequencies in Populations? In a population where the females have the allelic frequencies A = 0.35 and a = 0.65 and the frequencies for males are A = 0.1 and a = 0.9, how many generations will it take to reach HardyWeinberg equilibrium for both the allelic and the genotypic frequencies? Assume random mating and show the allelic and genotypic frequencies for each generation.arrow_forwardWhat does the Hardy-Weinberg model tell us about the factors that can change allele frequencies in populations and result in evolution? What are those factors, and what effect will they have on a biological population?arrow_forwardyou (should have) learned that selection alone cannot purge a population of the very last copy of a deleterious allele. If selection is unable to do so, which of the remaining mechanisms (of the five Hardy-Weinberg) assumptions is MOST LIKELY to do so? Justify your answer. That is, why is the mechanism you picked the most likely to get rid of that last copy of a harmful allele?arrow_forward
- A hypothetical population of 10,000 humans has 6848 individuals with the blood type AA, 2846 individuals with blood type AB, and 306 individuals with the blood type BB. What is the frequency of each genotype in this population? What is the frequency of the A allele? What is the frequency of the B allele? If the next generation contained 25,000 individuals, how many individuals would have blood type BB, assuming the population is in Hardy-Weinberg equilibrium?arrow_forwardWhen we take, say, 100 individuals of a species of beetle from the wild and place them in a new environment that is not so different that they are unable to thrive but different enough so that they are experiencing a new selective regime, say, a lower temperature, what typically happens? A - Sexual selection causes some larvae to be able to survive in the cooler temperatures and other individuals to be unable to survive because they need warmer temperatures. B - We are unable to measure phenotypic selection, presumably because we do not have much variation among individuals for how they handle temperature. C - The founder event assures us that the new population will be strictly representative of the source population (especially if we took all the 100 from the same location rather that from throughout the range of the species). D - The population evolves to be tolerant of the lower temperature; it can do this because of latent variation already in the 100 founding individuals. E -…arrow_forwardIn a population of 2000 ladybugs at equilibrium, there are 1120 ladybugs with eight spots (SS), 30 with six spots (Ss), and 850 with four spots (ss). If random mating were to occur within the ladybug population, with no mutations, gene flow, or natural selection taking place, what would you expect the frequency of q to be in the next generation?arrow_forward
- The trait that natural selection “selects for” is lifetime Darwinian fitness. If relative matching of the moths to the background is determining fitness differences, is there any difference in other fitness components in the color morphs of Biston betularia that is influencing the direction of evolution in the three populations shown in the graph? Give a reason for your answer.arrow_forwardWhich evolutionary forces a. cause an increase in genetic variation both within and between populations? b. cause a decrease in genetic variation both within and between populations? c. cause an increase in genetic variation within populations but cause a decrease in genetic variation between populations?arrow_forwardAssume that the frequency of gene B in a hypothetical population Is 0.63, that there are only two alleles (B and b) of the gee in the population, that allele B is dominant over allele b, that neither allele has a selective advantage over the other, and that the population is at equilibrium with regard to this particular gene. And how many individuals in this population are expected to be of genotype BB according to the Hardy-Weinberg formula? (Assume that the total population size is 150) 71 52 118 60 131arrow_forward
- If you had measured a set of morphological traits (beak depth, wing length, leg length, tail length, body size) in both the parent and offspring generations, would it be useful to measure any changes in these traits in the parent generation after the drought killed the birds with shallower beaks? Could any such changes measure a correlated response to natural selection on beak depth? Why or why not?arrow_forwardif a population of jumping spiders consists of 40 females and 40 males, what is the effective population size? Give the appropriate equation and show your work. Will genetic drift be an important evolutionary force in this population? Why or why not? If your answer is "yes", what does genetic drift do to allele frequencies? If your answer is "no", name two forces other than genetic drift that might be important in determining allele frequencies. asaparrow_forwardWhat is the Evidence That Populations Evolve by Natural Selection?arrow_forward
