Answer is to achieve genetic recombination. Please read this featured answer to know more.
Explanation:
Crossing over takes place during Meiosis I of gamete formation.
There is physical exchange of chromosomal parts between non-sister chromatids of homologous chromosomes during crossing over.
The process helps to produce new allelic recombination. After Meiosis II, of all the gametes produced, maximum of 50% receive recombinants.
