scientists are looking to determine the primary productivity of a lake by analyzing its oxygen no primary productivity. how are scientists able to measure how much oxygen is used during a plant’s cellular respiration process

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.
