QUESTION 12 Which of the following statements is TRUE? Recombination mapping experiments become more accurate as the distance between genes increases. The higher the coefficient of coincidence, the higher the degree of interference. Linked genes always exhibit recombination frequencies of greater than 50%. Positive interference occurs when a crossover in one region of a chromosome interferes with crossovers in nearby regions. Two genes that are located far from each other on the same chromosome will show a lower frequency of recombination than two genes that are close together on the chromosome. QUESTION 13 In a population of 10000 people, 8 women are red/green color blind (X-LINKED). Assuming the population is in equilibrium, how many males would be expected to be afflicted? (Assume the population is 50% men and women.) 800 100 10 400 200 QUESTION 14 Pick the statement about chromosome structure that is FALSE Gene duplications provide an explanation for the origin of gene families. A position effect occurs when a gene’s expression is altered by virtue of a change in its chromosomal position. Inversions increase the frequency of recombinate gametes. Genes that function abnormally when present in only one copy are called haploinsufficient. A pericentric inversion is one whose break points include the centromere. QUESTION 15 X, Y and Z are three linked genes, X and Y are separated by 40cm and Y and Z are separated by 10 CM. A women with the genotype XYZ/XYz marries a man with the genotype xyz/xyz. What is the probability of producing a child with the XYz phenotype assuming the interference is zero? 496 196 996 13.5% 1.5% QUESTION 16 Consider a population of 100 individuals and the frequency of the A allele is p = 0.6 and the frequency of the a allele is q = 0.4. If the following fitness values for each genotype are applied to the next generation, what will be the frequency of the “a” allele in the next generation? WAA = 1.0 WAa = 5 Waa = 25 36 Od 33 .28 25 .22 QUESTION 17 Farmer John decides to increase the weight of the eggs produced by his chickens. The average weight of his eggs is 50 grams. He knows that the heritability of egg weight is 0.5. He selects for chickens producing eggs that are 58 grams. The expected average weight of the resulting eggs is: 54 55 52 56 52 OOO 56 57 QUESTION 18 XXXXY can only occur because of a normal gamete fusing with a gamete which is the result of nondisjunction in: Melosis il in female Meiosis l in female Meiosis I and II in male Meiosis II in male Meiosis I and II in female ООООО QUESTION 19 75 In a population of 1000 the number of people having the following blood genotypes was measured.
