3. You experimentally manipulate a gene related to bacterial metabolism in the lab. You believe the mutant allele, A (delta), provides an advantage over the naturally occurring, W (wildtype), allele in resource-limited environments. Starting with a population in HW equilibrium with each allele equally represented, you record the genotypes of the surviving population after selection by this resource-limited environment occurs. What is the relative fitness of each genotype? (15pts) + WW WA ΔΔ Total Starting Count 250 500 250 1000 Surviving Count 33 205 200

20. A large population of laboratory animals has been allowed to breed randomly for a number of generations. After several generations, 25% of the animals display a recessive trait (aa), the same percentage as at the beginning of the breeding program. The rest of the animals show the dominant phenotype, with heterozygotes indistinguishable from the homozygous dominants. What proportion of the population is probably heterozygous (Aa) for this trait? (LS3-3) * 0.05 0.25 0.50 O 0.75
1. What is the expected time to fixation in generations for a new mutation in a diploid population (like humans) with an effective population size of 50? This new mutation is neutral and has no impact on fitness (e.g. synonymous polymorphism). Assuming the mutation isn’t lost immediately, will it reach fixation faster in a population of Ne=500 or Ne=5,000 and why?
Panthers are also susceptible to a respiratory infection [feline calicivirus]. Individuals in a population, who are homozygous dominant or heterozygous for genes encoding parasite or pathogen resistance, are more likely to resist an infection or parasite. Currently, population estimates of the Florida panther range from 100 – 160 individuals. Let’s assume that the population equals 160. During a particularly bad calicivirus outbreak, 40 Florida panthers die as a result of the infection. Using this information, answer the following questions utilizing the Hardy – Weinberg equation when necessary. What is the most likely genotype of the affected panthers that died from the respiratory infection? Use the letter “A” for your symbol. 2. What percentage of the population is most likely resistant to the calicivirus infection?
66)Parasites are organisms that make a living at the expense of another organism called a host. In populations of hosts and parasites, not all the possible parasite genotypes can successfully infect all the possible host genotypes. The most successful parasite genotypes (i.e. those with the highest fitness) are those that can exploit the most common host genotypes. As a result, the most common host genotypes suffer a decline in fitness. Meanwhile, rare host genotypes are relatively unaffected by parasites and thus enjoy a higher fitness which causes them to become more common. As a host genotype becomes more common, it also becomes a bigger target for parasites and eventually experience a decline in fitness. This is a case of Stabilizing selection Negative frequency dependent selection Disruptive selection Purifying selection Heterozygote advantage
