Meiosis includes a phase of genetic recombination via chromosomal crossover, wherein locations of DNA are exchanged concerning matched pairs of chromosomes, to sort new chromosomes, Just about every which has a new blend of the genes with the parents. Then the chromosomes are separated into one sets from the gametes.
