Anondisjunction in meiosis i would result in generation of:

a- two normal and two abnormal gametes
b- one normal and three abnormal gametes
c- one abnormal and one normal gametes
d- four abnormal gametes

option D - Four abnormal gametes

Explanation:

Nondisjunction occurs in the Anaphase phase of Meiosis I. It happens that at least ONE pair of homologous chromosomes FAIL to separate, resulting in two daughter cells having an EXTRA copy of one chromosome (e.g XXY) and two cells that are missing that chromosome (e.g XO).

Thus, Nondisjunction results in Four (4) abnormal gametes

the corpus luteum secretes estrogens and progesterone. the latter hormone causes changes in the uterus that make it more suitable for implantation of the fertilized ovum and the nourishment of the embryo. if the egg is not fertilized, the corpus luteum becomes inactive after 10–14 days, and menstruation occurs.

i hope this : )

the endomembrane system i think
