Required Question Y Question T The ability to taste certain substances, such as PTC is also genetically controlled. People that can taste have a dominant allele (T), while non-tasters have the recessive alleles (tt). Suppose a woman who is a non-PTC-taster has offspring with a man who is a homozygous PTC taster. What is the probability that they have a child with the tasting gene? O 25% 850% © 75% O100%

QUESTION 3 Linkage disequilibrium is defined by which of the following? O Positions in the genome where people vary by a single nucleotide base O The occurrence of two alleles in the repulsion configuration O The probability that two genes are linked O Crossing over that occurs between two genes that are located close to each other O The nonrandom association between alleles in a haplotype QUESTION 4 Red-green color blindness is a human recessive X-linked disorder. A young man with a 47, XXY karyotype (Klinefelter syndrome) is colorblind. His mother and father have normal color vision, but his mother has a father who is colorblind Did the nondisjunction event that gave rise to the young man with Klinefelter syndrome happen in the mother, the father or is it impossible to tell (assume that no crossing over took place in prophase I of meiosis)? a. Mother b. Father c. Impossible to tell Did this nondisjunction happen during Meiosis I, Meiosis II, or is it impossible to tell? a. Meiosis I…

QUESTION 7 A trihybrid individual with the genotype AaDdEe is testcrossed with an aaddee individual. The resulting offspring are as follows: ADe 880 aDE 67 AdE 45 ade 4 ADE 3 aDe 57 Ade 57 adE 887 Total = 2000 a) Determine the allele arrangement and gene order in the trihybrid parent. Give your answer using the PQr/pqR notation. b) Draw a chromosome map for these genes. Give your map distances to two decimal places. (Use underline or underscore (_) to draw the line for the map)
