In whom did non-disjunction occur? In meiosis I or meiosis II?

a. Woman; meiosis I
b. Woman; meiosis II
c. Man; meiosis I
d. Man; meiosis II
e. Woman; there is not enough information to tell if the nondisjunction happened in meiosis I or II.

e.Woman; there is not enough information to tell if the nondisjunction happened in meiosis I or II.

Explanation: There is not enough information to tell if the nondisjunction happened in meiosis I or II. Nondisjunction can occur during meiosis I and meiosis II, resulting in abnormal chromosomes number of gametes. The important difference between nondisjunction in meiosis 1 and Ii is that during meiosis 1, homologous chromosomes fail to separate while in meiosis II, sister chromatids fail to separate meaning it could have happened in meiosis I or II but we were not given.

the menstrual cycle – higher tier. negative feedback mechanisms affect the production of hormones in the menstrual cycle. oestrogen also stimulates the release of lh (luteinising hormone) from the pituitary gland, which in turn controls the production of progesterone.
