Hi, I'm having some trouble with this practice problem from my study guide. If anyone can explain it it would be very helpful! Sometimes nondisjunction will occur in a parent that has normal chromosome numbers and result in an offspring that has abnormal number of chromosomes. The phenotype of the affected offspring will often allow geneticists to determine in which parent and during which division of meiosis the nondisjunction occurred. In each of the examples below, assume the parents have a normal diploid chromosome complement. A man with the X-linked dominant condition “brown tooth enamel” and a woman with normal tooth enamel produce a son with brown tooth enamel. Let’s call the allele for brown tooth enamel “XB” and normal tooth enamel “Xb”. EXAMPLE 1: The parents in the family above produce another son, this time with two Y chromosomes and normal tooth enamel. In which parent did the nondisjunction occur? Explain and/or illustrate. Did nondisjunction occur at meiosis I or II?…

In mammals, there are two sex chromosomes, X and Y, which behave like homologous chromosomes during meiosis. Normal males have one X chromosome and one Y chromosome, and normal females have two X chromosomes. Males with an extra Y chromosome (XYY) occasionally are found due to inappropriate segregation of the chromosomes (i.e. non-disjunction). Which of the following could give rise to such an XYY male? Answer Yes or No for each situation. nondisjunction in the first meiotic division of spermatogenesis; normal meiosis in the mother nondisjunction in the second meiotic division of spermatogenesis; normal meiosis in the mother nondisjunction in the first meiotic division of oogenesis; normal meiosis in the father nondisjunction in the second meiotic division of oogenesis; normal meiosis in the father
Draw a diagram to show how nondisjunction of all chromosomesduring meiosis I in one parent could lead to polyploid offspring.(Use 2n = 6 for the starting cells; assume the other parent’s gametecontributes the normal number of chromosomes.)
