Detailed explanation-1: -Recombination in meiosis. Recombination occurs when two molecules of DNA exchange pieces of their genetic material with each other. One of the most notable examples of recombination takes place during meiosis (specifically, during prophase I), when homologous chromosomes line up in pairs and swap segments of DNA.

Detailed explanation-2: -The exchange of genetic material (DNA) between the non-sister chromatids of the homologous chromosomes is known as crossing over. It leads to the recombination of genetic material which involves a mutual exchange of the corresponding segments of non-sister chromatids of homologous chromosomes.

Detailed explanation-3: -Genetic recombination is a process that occurs during meiosis, which is the type of cell division that produces gametes. During this process, homologous chromosomes pair up and form a unit called a tetrad. The chromosomes can then cross over and exchange genetic material, which results in new combinations of alleles.
