A conservation biologist studied four generations of a population of rare Ethiopian jackals. When the study began, there were 47 jackals in the population, and microsatellite analysis showed a heterozygosity of 0.55. In the second generation, an outbreak of distemper occurred in the population, and only 17 animals survived to adulthood. These jackals produced 20 surviving offspring, which in turn gave rise to 35 progeny in the fourth generation. a) What was the effective population size for the four generations of this study? b) Based on its effective population size (use the rounded off value you obtained in a), what is the heterozygosity of the jackal population in generation 4 (t=4)? c) What is the inbreeding coefficient in generation 4, assuming an inbreeding coefficient of F = O at the beginning of the study (t=1), no change in microsatellite allele frequencies in the gene pool, and random mating in all generations?

Microbiologists have discovered that alleles associated with antibiotic resistance are present in bacteria that live in soil, even in environments that are comparatively free of antibiotic pollution from human activities. Why are such alleles present (albeit at low levels) in bacterial populations? Conversely, if resistance alleles are beneficial, why are they rare in natural populations of bacteria?
A neutral mutation arises in a diploid population of 10,000 individuals. Use this information to answer the following questions. a) What is the probability that the neutral allele goes to fixation? b) Assuming that the neutral mutation eventually goes to fixation, what is the expected time to fixation (in generations)?
(a) Assuming that Migaloo’s albinism is caused by a rare recessive gene, what would be the likelihood of the establishment of a natural robust subpopulation of albino white humpback whales in this population? (b) Assuming that Migaloo’s albinism is caused by a rare dominant gene, what would be the likelihood of the establishment of a natural robust subpopulation of albino white humpback whales in this population?

A population of 30 individuals has a mutation that generates a new allele “a”. This new allele gives a nearly identical phenotype to the “old” allele “A”. What is the probability of fixation for “a”? What will be the average number of generations until fixation? How would these values change if the population contained 3000 individuals?
Two SNPs are located in the short arm of chromosome 12. SNP1 has allele frequencies of 60% T and 40% C, and SNP2 has allele frequencies of 40% A and 60% G. What is the frequency of the haplotype T-G in a population if the two SNPs are in absolute linkage disequilibrium and if they are in linkage equilibrium?
