Recombination is a source of genetic variation that involves the swapping of sections of chromosomes during meiosis.

Explanation:

Cell division is of 2 types one is the mitosis division of body cells and meiosis that is division of germ cell. The meiosis involves production of haploid gametes, these gametes fuse with each other and form a diploid zygote, and accordingly the formation of gametes involves the mixing of 2 different cells with homologous chromosomes.

Recombination is the result of crossing over of cells. When these cells fuse they give rise to a new gamete with characters mixed from both the cells.
