Nondisjunction during meiosis i results in
a. one pole of the cell receiving neither member of a homologous pair of chromosomes
b. a change in the status of a daughter cell fom haploid to diploid
c. the generation of an extra daughter cell
d. a gamete that cannot fuse with another gamete
e. a change in the status of a daughter cell from diploid to haploid

a. one pole of the cell receiving neither member of a homologous pair of chromosomes

Explanation:

Normally during meiosis I homologous chromosomes pair, crossover and then separate from one another. Each of the two daughter cells resulting from meiosis I receive one chromosome from the pair.

If there is non-disjunction during meiosis I, both homologous chromosomes will migrate together to one of the poles of the cell, and the other pole will receive neither chromosome from that pair.
