Based on the class data from Experiment I, generally speaking, how does population size affect genetic drift?

2. You have sampled a population in which you know that the percentage of the homozygous recessive genotype (a) is 26%. Using that 26%, calculate the following: A. The frequency of the "aa" genotype. B. The frequency of the "a" allele. C. The frequency of the "A" allele. D. The frequencies of the genotypes "AA" and "Aa." E. The frequencies of the two possible phenotypes if "A" is completely dominant over "a

1. According karacan 2014, which of the following statement is true about the level of generativity? 2.

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? A. The peak would move to the left. B. The peak would move to the right. C. The peak would become taller and narrower. D. The peak would become lower and more rounded. EducationTM Inc. Aouenber

5) A mutant red coat color allele (Yr) arises in island B and is present in the adult population in a heterozygous individual in the population of 117 adults of year 2000. Yr is recessive to the other alleles at the Y locus. What is the probability (p) that, purely by the action of genetic drift, the allele will rise to fixation (reaching a frequency of 1.0) at some time in the future? (A)  0.0 < p  < 0.2                   (B)  0.2 < p  < 0.4                   (C)  0.4 < p  < 0.6       (D)  0.6 < p  < 0.8                   (E)  0.8 < p  < 1.05 6) For the same genetic scenario, what if the single red allele arose in the island A and was present by 1990 in a heterozygous individual, one of a population 12 individuals. Would this red mutant allele have a better or worse chance of rising to fixation relative to the island B population of problem 5? (A) red allele more likely to reach fixation in A island beginning in 1990 compared to B island beginning in…

1. Based on the class data from Experiment I, for each of the three populations, describethe effect of population size on genetic diversity over time. Your answer should touchon the magnitude of any genetic changes through time for each of the three populationsizes.

e. The frequencies of the genotype "Aa." f. The frequency of the recessive phenotype if "A" is completely dominant over "a." g. The frequency of the dominant phenotype if "A" is completely dominant over "a".

11. A lecture hall of 1000 students conducts the same allele frequency simulation that we conducted in class with the A and a cards. In the beginning, everyone starts as Aa. The following data was collected; what is the most likely explanation for the results? a. natural selection against AA b. genetic drift c. mutation pogos Generation 0 1 2 %A %0 .5 9
