2. Wild salmon are tetraploid (ploidy number = 4) and reproduce sexually. Suppose the h allele is completely recessive, meaning that it only affects the phenotypes of hhhh salmon. (20 pts) a. Suppose frequency(h) = 0.3 According to the Hardy-Weinberg model, what is the expected frequency of hhhh salmon? Explain your reasoning. b. If the salmon population is inbreeding, how does this change the expected frequency of hhhh salmon? Circle one, and explain. increases / decreases / no change / depends c. How does inbreeding affect the strength of selection on the hallele? stronger / weaker / no change / depends Circle one, and explain. d. Is inbreeding considered a mechanism of evolution? Circle one, and explain. yes no depends e. AquAdvantage salmon are triploid (ploidy number = 3). Is the Hardy-Weinberg model useful for analyzing AquAdvantage salmon populations? yes no / depends Circle one, and explain.

Answer 1

Answer: page-1 * According to data- According to Hardy - weinberg model expeded frequency of hhh salmon will be que = 0.3x0.3x0:3X0:3 -0.0081 According to Haddy weinberg equiliboium p=2+2P2= This is for AA genotype here four given allele So pa tq" + 4 p q +6 pt2 +4Pq3 so frequency of hhh will be 0.0081 b) It will increase it as inboeeding increase Homozygosity. c) It is stronger as in boeeding expoess the recessive allele d) No inbreeding is mating between relative it increase homozygosity does not cause evolution e) organism should be diploid. so No.
