-Genetic recombination is the process by which two different DNA are disintegrated and recombined to form new pairs of alleles. The process of recombination also involves the breakage and rejoining of parental chromosome. It occurs during meiosis ( that is formation of sperm and egg cells) and it gives them the correct number if chromosomes). Recombination occurs in meiosis through:
- CROSSING OVER: this is when paired chromosome press together and break, each may swap a portion of its genetic material.
- INDEPENDENT ASSORTMENT: which is the chromosome invented from either the father or mother can sort into any gamete and this produces a tremendous genetic variation. I hope this helps, thanks!
