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 b. Meiosis II c. Impossible to tell

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
b. Meiosis II
c. Impossible to tell
