In the 1890s, hunting reduced the northern elephant seal population to only 20 individuals. Due to conservation efforts, their population size today is above 30,000. How would the genetic diversity of the northern elephant seal population compare to the genetic diversity of the southern elephant seal population, which was not heavily hunted?* The northern elephant seal would have much less genetic varlation than the southern elephant seal. The southern elephant sea would have much less genetic variation than the northern elephant seal. O The two populations would have similar genetic variation The southern elephant seal would have stable genetic variation because it is in Hardy- Weinberg equilibrium. O O O 0

Mountain gorillas are a highly endangered primate species, with 800 or so individuals surviving in the two remaining populations. A recent sampling of mountain gorilla genomes revealed a very low level of genetic diversity. Explain why a decline in genetic diversity often accompanies a decline in population size.

One concept of conservation biology is known as minimum viablepopulation. Some species’ populations are so fragmented andsmall that they may have very little genetic variability left. Withminimal genetic variation in the population, there is little likelihoodthat a population can adapt to an environmental threat, such as anew disease. Florida panthers are at or below the minimum viablepopulation level (estimated population less than 80). 1)Do you think that it is practical to use limited resources toconserve a population like the Florida panther? 2)Why?
