Detailed explanation-1: -What stage of meiosis does independent assortment occur? Independent assortment in meiosis takes place in eukaryotes during metaphase I of meiotic division. It produces a gamete carrying mixed chromosomes. Gametes contain half the number of regular chromosomes in a diploid somatic 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: -Homologous pairs of chromosomes line up at the metaphase plate during metaphase I of meiosis. The homologous chromosomes, with their different versions of each gene, are randomly segregated into daughter nuclei, resulting in a variety of possible genetic arrangements.

Detailed explanation-4: -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.

Detailed explanation-5: -Sister chromatids separate in meiosis II. Independent assortment of genes is due to the random orientation of pairs of homologous chromosomes in meiosis I.
