Explain the relationship between the crossing over and genetic variation

Meiosis and Genetic Variation. When homologous chromosomes form pairs during prophase I ofmeiosis I, crossing-over can occur.Crossing-over is the exchange of genetic material between non-sister chromatids of homologous chromosomes. It results in new combinations of genes on each chromosome.

Answer:

Crossing over is the phenomena of the process of exchange of genetic material between the non sister chromatids of the homologous chromosomes.

The crossing over results in production of the new recombination. This produces the genetic variation in the individual that may be harmful or beneficial. The process of crossing over provides the way by which the genetic variation can be introduced in the organism.
