- Distinguish between prezygotic and postzygotic isolating mechanisms, and provide an example of each.arrow_forwardIf (positive) assortative mating increases in a population, what would expect to happen to genotype frequency over generations? O a) Frequency of the heterozygous genotype will increase. b) Frequency of the homozygous genotypes will decrease. O c) Frequency of the homozygous genotypes will increase. O d) There will be no change in genotype frequency.arrow_forwardWhat long-term effects can gene flow have on any two populations that are exchanging genes? View keyboard shortcutsarrow_forward
- What is inbreeding depression and why is it particularly a concern for conservation biology? A) It is a chemical imbalance in the brain of animals forced into close quarters, such as those rescued from the wild and placed in zoos. B) It is a situation where the frequency of an allele over time depends greatly upon its initial frequency, as such if populations are too small, the present alleles are at risk of being lost. C) It is a situation where offspring of genetic relatives have increased fitness, this occurs when populations of animals are large and they mate freely. D) It is a situation where offspring of genetic relatives have reduced fitness, this occurs when populations of animals become too small and they are thus likely to mate with closely related individuals.arrow_forwardDescribe the effect of malaria on the frequency of the HbS allele in areas where malaria is common:In areas with malaria, which individual would survive better and leave more offspring- an individual with two HbA alleles or an individual with one HbA allele and one HbS allele? Given this, would you expect the HbS allele to be common or rare in populations living with malaria?arrow_forwardIn a certain population in the US, the frequency of CCR5-Δ32 homozygous individuals is 1%. Assuming genetic equilibrium, what is the frequency of heterozygotes in this population?arrow_forward
- Anisogamy is the term for sexual dimorphism in gamete size. a) Discuss the evolution of anisogamy from an ancestor in which gametes had equal size. What factors would lead to a divergence in gamete size among members of a population? b) Sexual selection can be strong in some species, and weaker in others. What determines the strength of sexual selection for a certain species? Discuss the differences in sex roles and Bateman’s Principle in your answer.arrow_forwardHow does bottleneck effect relate to the founder effect? is the founder effect a consequence of the bottleneck effect?arrow_forwardRefer to the figure above. In their investigation of natural selection on Mc1r alleles (the gene that determines coat color) in Arizona pocket mice, Hoekstra et al. determined the frequency of the D and d alleles in each population. They also determined the frequency of alleles for two neutral mitochondrial DNA genes (genes that do not affect and are not linked to coat color). Why did the researchers include the mitochondrial DNA genes as part of their experimental design? Allele change for the neutral mitochondrial genes serves as an experimental group and gives information on any general background genetic difference among these populations. Allele change for the neutral mitochondrial genes serves as a control and determines coat-color differences among these populations. Allele change for the neutral mitochondrial genes serves as an experimental group and gives information on coat-color differences among these populations. Allele…arrow_forward
- I've observed varying egg mimic sizes on female fins: large, small, or none. I found that this trait follows Mendelian genetics with a single locus having two alleles: BB (large mimic), Bb (small mimic), and bb (no mimic). During a recent collection trip, we gathered 211 males with large egg mimics, 156 with small mimics, and 28 with no mimics. Is the locus in Hardy-Weinberg equilibrium, and what's the expected frequency of the small egg mimic phenotype in this population? 1.Yes it is in HW equilibrium, expected = 0.07 2.Yes it is in HW equilibrium, expected = 0.39 3.No it is not in HW equilibrium, expected = 0.53 4.No it is not in HW equilibrium, expected = 0.20 5.No it is not in HW equilibrium, expected = 1.0arrow_forwardThe agouti gene determines coat colour in mice. Heterozygous mice have yellow coats, while homozygous dominant mice have black coats. However, having two copies of the recessive alleles is lethal. In a population of 2 000 mice, 1 082 mice have black coats. a) Calculate the frequency of each allele. Show all your work and express your answer as a value between 0 and 1 rounded to two decimal places. b) What percentage of the mouse population is expected to be carriers of the lethal allele? Show all your work and express your answer rounded to one decimal place. c) How many mice will die during fetal development? Show all your work and round your answer to the closest whole number.arrow_forwardDescribe the competing selective forces acting on peacock tails. Together, do these selective forces produce disruptive, directional, or stabilizing selection?arrow_forward
