Answer:
Crossing over
Explanation;
-Meiosis is the type of cell division that takes place in the germ line cells which results in the production of haploid cells called gametes.
-One of the advantage of meiosis is that it results to genetic variation thus creating genetically unique reproductive cell types. Genetic variation occurs due to the process of cross over in which homologous chromosomes exchange genetic materials through the chiasmata. It involves the exchange of segments of chromosomes between non sister chromatids.
