In a population of mountain lions, 9% of the individuals suffer from a disease caused by a recessive allele (aa). A) Calculate the frequency of both the dominant and recessive alleles. B) What is the percentage of homozygous dominant individuals and what is the percentage of heterozygous individuals in the population?
Population genetics is the study of: a. how selective forces change the allele frequencies in a population over time b. the genetic basis of population-wide traits c. whether traits have a genetic basis d. the degree of inbreeding in a population
The continued presence of the allele that causes sickle cell anemia in areas where falciparum malaria is prevalent demonstrates which of the following phenomena? (a) inbreeding depression (b) frequency-dependent selection (c) heterozygote advantage (d) genetic drift (e) a genetic bottleneck
Which statement best summarizes why genetic drift tends to impact small populations more than large populations? A. Small populations have a heterozygote advantage because heterozygotes are more common than homozygotes. B. Small populations have a smaller gene pool, so random changes influence them more. C. Small populations have a relatively large gene pool, so the founder effect stabilizes their alleles.D. Small populations tend to experience directional selection, making one phenotype more common.
Which statement about Inbreeding (=consanguinity) is correct? a. Inbreeding has no influence on the degree of homozygosity. b. Inbreeding increases the frequency of homozygotes in a population. c. Inbreeding improves the overall biological fitness of progeny. d. Inbreeding increases the frequency of heterozygotes in a population.
Assuming a population is in Hardy-Weinberg equilibrium, an increase in the frequency of the p(A) allele from 0.6 to 0.9 would result in which of the following outcomes? a. A decrease in the number of homozygous dominant individuals within the population b. A decrease in the number of homozygous recessive individuals within the population c. An increase in the number of homozygous recessive individuals within the population d. An increase in the number of heterozygotes within the population e. No change in genotypic frequency within the population
A farmer performs truncation selection to try to increase the weight of peaches in his orchard. Which statement correctly describes a possible outcome of this selection? a) If peach weight is not heritable, the average weight in the next generation will increase. b) If peach weight is heritable, the average weight in the next generation will increase. c) The average peach weight will decrease due to this inbreeding. If peach weight is heritable, the average weight in the next generation will decrease.
