Detailed explanation-1: -Crossing over occurs when chromosomal homologs exchange information during metaphase of Meiosis I. During this stage, homologous chromosomes line up on the metaphase plate and exchange genetic information.

Detailed explanation-2: -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-3: -Another feature of of independent assortment is recombination. Recombination occurs during meiosis and is a process that breaks and recombines pieces of DNA to produce new combinations of genes.

Detailed explanation-4: -During metaphase of meiosis I, synapsed pairs of homologous chromosomes (known as bivalents or tetrads) are lined up on an imaginary plane in the middle of the cell called the metaphase plate. The chromosomes are attached to spindle fibres at their centromeres.
