- The original source of new alleles, upon which selection operates,is mutation, a random event that occurs without regard to selectionalvalue in the organism. Although many model organismshave been used to study mutational events in populations, someinvestigators have developed abiotic molecular models. Soll et al.(2006. Genetics 175:267–275) examined one such model to studythe relationship between both deleterious and advantageousmutations and population size in a ligase molecule composed ofRNA (a ribozyme). Soll found that the smaller the population ofmolecules, the more likely it was that not only deleterious mutationsbut also advantageous mutations would disappear. Whywould population size influence the survival of both types ofmutations (deleterious and advantageous) in populations?The ratio of nonsynonymous differences pernonsynonymous site, dN, to synonymous differences per synonymous site, dS, can be usedto test for positive selection Imagine that in a duplicate pair of loci, oneparalog is evolving neutrally while the other isevolving under strong positive selection. Whatspecific data are needed to detect that situationusing the dN/dS ratio, and what pattern do youexpect to see?According to Hamilton's Rule, in which scenario is selection for cooperative breeding expected to be the strongest? but lose the chance to have Helpers raise and increase the survival and reproduction of of their own offspring. O 100 additional 2nd cousins twice removed to whom they are 0.00781 (0.781%) genetically related; 2 of their own offspring. 60 additional 1st cousins once-removed to whom they are 0.0625 (6.25%) genetically related; 1 of their own offspring. O 50 additional grandnieces/nephews to whom they are 0.125 (12.5%) genetically related; 2 of their own offspring. None of the three scenarios are likely to result in the evolution of cooperative breeding according to Hamilton's Rule.
- /hich of the following is an example of disruptive selection? O Short weeds that grow close to the height O Dark-colored moths that hl survive to reprodWhich type of selection best describes the shift in peppered moth from the light form to the dark form following the industrial revolution? Directional Stabilizing Disruptive 58Stabilizing selection happens when O Large and small values of a trait are selected against Medium values of a trait are selected against Only large OR small values of a trait are selected against
- 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 advantageUnder which of the following scenarios would variation be maintained? Selection acting on a dominant high fitness allele Selection acting on a recessive high fitness allele Selection favoring heterozygotes Selection acting against heterozygotes None of the aboveSelection operates on a trait with a normal distribution. If after selection, the mean in the trait has not changed, but the frequency In the trait has increased at the extremes, of: O disruptive (or diversifying) selection O directional selection O stabilizing selection O frequency-dependent selection
- If female rabbits prefer longer eared males, but shorter eared males are less likely to acquire life- threatening infections of the ear, what overall pattern of selection should be observed when these processes happen together? disruptive directional stabilizing O balancingIn the following form of selection, one extreme of a variable character is selected for: Directional Selection Stabilizing Selection Disruptive SelectionWhat are two reasons why a selection limit is reached in which artificial selection no longer has an effect?
