- Genetic drift can produce large changes in allele frequencies in a short time period. true or falseThe evolution of a qualitative trait in reponse to natural selection is described by the following equation, R=h2 S a) What is S and what does it measure? b) Describe a study that woukd allow you to estimate S in a real population.Most commonly, individuals of a population show a _______ distribution within their habitat. a. clumped b. random c. nearly uniform d. none of the above
- If a populations allele and genotype frequencies remain constant from generation to generation, (a) the population is undergoing evolutionary change (b) the population is said to be at genetic equilibrium (c) microevolution has taken place (d) directional selection is occurring, but only for a few generations (e) genetic drift is a significant evolutionary forcehow can a small popoulation/high genetic drift "help" ab eneficial allele become fixed?DNA typing is used to compare evidence DNA (E) left at a crime scene to two suspects(S1 and S2). Suspect 1 is excluded by the evidence, but suspect 2 remains included. What isthe frequency of suspect 2's genotype if the allelic frequencies in the population are f(A1) =0.1, f(A2) = 0.2, and f(A3) = 0.7, and the population is at Hardy–Weinberg equilibrium?I do not need the answer, just HOW you do it. I got 0.02 as the answer, but I know that isn't right.
- Small population size causes genetic drift because ofchance sampling of different alleles from one generation to the next. We can predict how much geneticdrift occurs for a given population size using binomialsampling statistics. With a population of size N, wecan estimate that 95% of the time the allele frequency(p) in the next generation will be withinthe confidence interval of p ± 1.96 (√p(1 − p)2N ),where p(1 − p)2Nis an estimate of the statistical variancein allele frequencies from one generation to the nextwith random sampling of 2N alleles each generation. a. What is the confidence interval for p = 0.5 whenN = 100,000?b. What is the confidence interval for p = 0.5 whenN = 10?c. How are the results in parts (a) and (b) related tothe consequences of a population bottleneck?The frequency of two allele in a gene pool is 0.19 (W) and 0.81 (w). What is the percentage in the population of heterozygous individuals homozygous recessivesIn a large population of squirrels, 0.14 have the recessive genetic condition nlourianfilindr (fictional). Assume the Hardy-Weinberg distribution. What is the frequency of the dominant allele in this population? Giver your answer with two digits parts the decimal point.
- Which of the following is a factor that, by itself, does not promotewidespread changes in allele or genotype frequencies?a. New mutationb. Natural selectionc. Genetic driftd. Migratione. Nonrandom matingWhich of the following statements describes an example of genetic drift?a. Allele g for fat production increases in a small population because birds with more bodyfat have higher survivorship in a harsh winter.b. Random mutation increases the frequency of allele A in one population but not inanother.c. Allele R reaches a frequency of 1.0 because individuals with genotype rr are sterile.d. Allele m is lost when a virus kills all but a few individuals and just by chance, none ofthe survivors possess allele m.Which of the following is an example of genetic drift? peter Parker gets irradiated and turns into spider man as global temperatures increase alleles that confer resistance to heat become more prevalent the American bison was hunted almost to extinction very quickly and only a few remained 5% of your neighbourhood moves to Canada
