A crossover in meiosis is an exchange of genetic material between non-sister chromatids of homo-logous chromosomes (Option D). It increases genetic variation.

What is crossover?

Crossover or recombination refers to the exchange of genetic material between nos sister chromatids during Meiosis I.

This process (crossover) occurs in Prophase I of Meiosis I, i.e., during the first step of Meiosis I.

Crossover acts to increase the genetic variation of the resulting meiotic gametic (germinal) cells.

A crossover in meiosis is an exchange of genetic material between sister chromatids of homologous chromosomes.

When and where does Crossing Over take place?

The so-called chromosomal permutation or crossing over phenomenon refers to an exchange between homologous chromatids that occurs naturally and reciprocally. This type of translocation occurs during meiosis I of cell division, in the prophase I phase, more specifically in the pachytene subphase.

With this information, we can conclude that a crossover in meiosis is an exchange of genetic material between sister chromatids of homologous chromosomes.
