Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
When does independent assortment occur?
A
prophase 1
B
prophase 2
C
telophase 1 and telophase 2
D
metaphase 1 and anaphase 1
Explanation: 

Detailed explanation-1: -Answer and Explanation: The stage of meiosis where independent assortment occurs is metaphase I. Metaphase I is the first metaphase that occurs in meiosis where the tetrads of homologous chromosomes align at the middle of the cell.

Detailed explanation-2: -Independent assortment occurs in metaphase I and anaphase I, and is where the homologous chromosomes are randomly shuffled into the two daughter cells. Chromosome mutations are inherited.

Detailed explanation-3: -Independent assortment explains how different genes separate independently from one another during the development of reproductive cells. Yes, Independent assortment occurs in anaphase, specifically anaphase I of meiosis.

Detailed explanation-4: -Independent assortment takes place during the process of meiosis. In this process, the chromosomes are halved and are known as haploid.

Detailed explanation-5: -In metaphase I, the homologous pairs of chromosomes align on either side of the equatorial plate. Then, in anaphase I, the spindle fibers contract and pull the homologous pairs, each with two chromatids, away from each other and toward each pole of the cell. During telophase I, the chromosomes are enclosed in nuclei.
