Question

What does correct chromosome alignment in meiosis I require?

Answer 1

1. Meiosis I ( Also called Reduction division): The sexual reproduction of an organism is caused by the fusion of male and female germ cells (sperm or egg cells).
2. During the prophase of meiosis-I, homologous chromosomes pair and cross to form a bivalent chromosome.
3. At a later stage, the divalent attaches to the mitotic spindle and the homologue separates, reducing the number of chromosomes in half.
4. After mating, homologous centromeres appear to be aligned.

Thus, correct chromosome alignment requires attachment to the mitotic spindle.
