Which of the following is NOT a likely consequence of genetic drift in a small population? i) increase in frequency of both homozygotes at a locus ii) decrease in heterozygosity of a population iii) inbreeding depression iv) fluctuation in allele frequencies
Homework Answers
iii) inbreeding depression : it is the consequence of homozygosity and not genetic drift.
genetic drift is more prominent in small population because it alter the allele frequency , result in fixation of one allele and loss of other allele .
which result in increase homozygosity of the population and decrease in heterozygosity of the population.

QUESTION 4 1 points Save Answer One metric of genetic diversity in a population is heterozygosity, i.e., the frequency of heterozygotes. For the marker(s) that are not in Hardy-Weinberg equilibrium, does the difference between Ho and He indicate increased or decreased heterozygosity for those markers? Increased heterozygosity Decreased heterozygosity QUESTION 5 2 points Save Answer Select all the mechanisms of evolution that could explain the deviations from H-W expected frequencies for those markers, based on the difference in heterozygosity?

In a population of gorillas scientists sample the tyrosinase gene (tyr). The tyr+ allele results in normal pigmentation in both heterozygotes and homozygotes. The tyr- allele is recessive and results in albino homozygotes. DNA sampling indicates that the frequency of tyr+ is 0.9 and tyr- is 0.1. Pedigree studies indicate that the inbreeding coefficient is 0.3 in this population. What proportion of the population should be albino? How does this compare to expected frequency of albinos with the same allele frequencies but no inbreeding? If...

Q3.3. Recall the prediction: Allele frequencies change by genetic drift equally quickly in large populations and in small populations. Is this correct? Why or why not? Yes. Genetic drift is sampling error, and sampling error is unpredictable, no matter the population size. Yes. Small populations experience more sampling error, but large populations have more reproduction overall, leading to similar rates of allele frequency change. O No. In the ferret experiments, allele frequencies changed more quickly in the small populations than...

2. Which of the following correctly describes how inbreeding will affect genotype and allele frequencies in Hardy-Weinberg populations? Genotype and allele frequencies will be unaffected. The frequency of heterozygotes will decrease, but allele frequencies will be unaffected. The frequency of homozygotes will increase, and deleterious alleles will decrease. Beneficial alleles will increase in frequency, as well as the genotypes containing those alleles. Genotype frequencies will return to H-W expectations after 1 generation of random mating. 3. Consider a population with...
