Question

2. Wild salmon are tetraploid (ploidy number = 4) and reproduce sexually. Suppose the hallele is completely recessive, meaning that it only affects the phenotypes of hhhh salmon. (20 pts) a. Suppose frequencych) = 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, explain

Answer 1

(9) Acc. to Haridy - weinberg model frequency of the expected will be Salmon q4 0:3 *0.3 x0.3 0.3 → 0.0081 Acc. to haridy weinberg equilibrium pod +92 +9Pq=1 This is for AA genotype here four given do P4-94 + 403q +60292 +4P93 allele So 0.008+ fuequency of finth will be b) It will increase it as inbreeding increase Homozygosity It is stronger as necessive allele inbreeding exposes the dy NO is mating inbreeding increase homozygosity does not mating, between ouelative it Cause evolution ey organic lism should be diploid.
