if nondisjunction occurs during meiosis,
A. only two gametes may form instead of four.
B. some gametes may have an extra copy of some genes.
C. The gamete cannot join another to form an organism.
D. the gametes redistribute chromosomes after meiosis.

Nondisjunction is failure of segregation of chromosome during anaphase. It can occur during anaphase I or anaphase II of meiosis. Nondisjunction during anaphase I of meiosis would result in presence of both chromosomes of homologous pair in one daughter cell resulting in presence of extra copy of some genes. Similarly, non disjunction at anaphase II leads to presence of extra chromosome in some daughter cells.
