Leo, a chromosomally normal male, is married to Jane, who isalso chromosomally normal. They have a son who has Klinefeltersyndrome. Assuming that all other phases of cell division occurnormally, please indicate whether each of the following eventscould have produced the their son (assuming all other phases ofcell division occur normally).

**Please explain why/ or why not for each**

a. Non-disjunction in meiosis I in Mary

b. Non-disjunction in meiosis II in Mary

c. Non-disjunction in meiosis I in Leo

d. Non-disjunction in meiosis II in Leo

While working in a pathology lab, you are presented with a bovine blood sample (2n=60) that is suspected to have a genetic abnormality. You decide to karyotype the sample and diagnose trisomy 29. Assume two hypothetical genes A and B are located on chromosomes 28 and 29 respectively. How many alleles for each gene will be present in the Primary oocyte, secondary oocyte and ovum that produced the animal with the abnormal karyotype indicated above – Provide answers for all possible scenarios. (1.5 marks) Describe the number of chromosomes and chromatids in the Primary oocyte, Secondary oocyte and ovum that produced the animal with the abnormal karyotype indicated above – Provide answers for all possible scenarios. (1.5 marks) Another two hypothetical genes P and Q are located on chromosome 1; with the dominant alleles (P and Q) in repulsion phase, and recessive alleles (p and q) in repulsion phase on homologous chromosomes. Suppose a single crossing over occurs between the two genes during meiosis. What is the probability that the ovum that gave rise to karyotypically abnormal animal contains the dominant or recessive alleles in coupling phase? (1 mark) Suppose the animal had an XXY karyotype instead of trisomy 29. Did non-disjunction occur in the male or female parent (or both) and at which division(s), meiosis I or meiosis II? (1 mark)

While working in a pathology lab, you are presented with an ovine blood sample (2n=54) that is suspected to have a genetic abnormality. You decide to karyotype the sample and diagnose trisomy 24.
