Nondisjunction is when chromosomes do not separate correctly in anaphase. Nondisjunction in meiosis II produces A. two cells with too many chromosomes and two cells with too few chromosomes. B. two cells with the correct number of chromosomes and two cells with too many chromosomes. C. two cells with too many chromosomes; one with too many chromosomes and one with the correct number of chromosomes. D. two cells with the correct numbers of chromosomes; one cell with too many chromosomes and one cell with too few chromosomes.
Oogenesis
The formation of the ovum (mature female gamete) from undifferentiated germ cells is called oogenesis. This process takes place in the ovaries (female gonads). Oogenesis consists of three stages known as the multiplication phase, growth phase, and maturation phase.
Cell Division
Cell division involves the formation of new daughter cells from the parent cells. It is a part of the cell cycle that takes place in both prokaryotic and eukaryotic organisms. Cell division is required for three main reasons:

two cells with too many chromosomes; one with too many chromosomes and one with the correct number of chromosomes.
two cells with the correct numbers of chromosomes; one cell with too many chromosomes and one cell with too few chromosomes.
