What is inbreeding depression? Why is inbreeding depression a serious concern for animal biologists involved in species-conservation breeding programs?

Certain animal species, such as the black-footed ferret, are nearly extinct and currently exist only in captive populations. Other species, such as the panda, are also threatened but exist in the wild thanks to intensive captive breeding programs. What strategies would you suggest in the case of black-footed ferrets and in the case of pandas to monitor and minimize inbreeding depression?

If you were to compare your genome sequence with that of your parents, how would it differ? If you were to compare your genome sequence with another student's in the class, how would it differ? What additional difference might you see if your genome was compared with that of a sub-Saharan African, or if you are of sub-Saharan African descent, with that of a non-African?

Two populations of deer, one of them large and living in a mainland forest and the other small and inhabiting a forest on an island, regularly exchange members that migrate across a land bridge that connects the island to the mainland. In which population do you expect to see the greatest allele frequency change? Why?

The mtDNA sequence of Neanderthals is more similar to that of modern humans than to that of Denisovans. However, analyses of nuclear DNA clearly indicate that Neandertals and Denisovans share a more recent common ancestor than either of these hominins shares with modern humans. Propose a hypothesis to resolve the discrepancy between the mtDNA and the nuclear genome.

Genetic Analysis 20.1 predicts the number of individuals expected to have the blood group genotypes MM, MN, and NN. Perform a chi-square analysis using the number of people observed and expected in each blood-type category, and state whether the sample is in H-W equilibrium.
