- Natural selection tends to work toward genetic unity;the genotypes that are most fit produce the mostoffspring and increase the frequency of adaptive allelesin the population. Yet there remains a great deal ofvariability within the populations of species. Describethe factors that contribute to this genetic variability. Provide the link of referencesOf the statements provided, which one is true for Hardy-Weinberg Equilibrium (HWE)? O The population is evolving due to genetic drift. O Natural Selection is not occuring within the population. Op+q=1 calculates genotype frequencies. O Individuals within the population move back and forth between another nearby population.Natural Selection is an evolutionary force that acts at phenotypic and genetic level. At the genetic level, which of the following statements is correct about the action of this force: O Selection is random and doesn't need genetic diversity in the population O Selection decreases the genetic diversity in the population O Selection is always negative and makes traits undesirable O Selection creates new alleles in the population
- Which of the following is calculated as the survival rate of a genotype multiplied by the average number of offspring for individuals of that genotype? O Absolute Fitness O Mean Relative Fitness Selection Coefficient O Expected Genotype Frequency O Relative FitnessIf variation in a trait is only due to environmental variation, and not genetic variation, how will directional natural selection change that trait value through time? [select one]: O Natural selection is likely to cause that trait to evolve Can't tell from information provided O That trait will be eliminated O Natural selection will not cause that trait to evolveThe 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?
- Which of the following statements is false? ONatural selection can alter a population's mean trait value O Natural selection usually decreases or maintains genetic variation Natural selection always favours rare genotypes O Natural selection acts on the phenotypeIf a relative fitness value is w=0.4, what is the selection coeffcient used to identify the differences between the fitness of organisms wiht different traits?Ecalogical seleation Sexual selection What is ecological selection?
