![]() ![]() ![]() When one of the parents has a genetic defect, recombination through meiosis can replace that abnormality in the next generation, allowing the formation of a healthy individual. Repairs genetic defects: The process of mixing chromosomes in meiosis, commonly known as recombination, helps repair genetic abnormalities in individuals produced through meiosis.These variations form the basis of the evolutionary process. Creates genetic diversity: The exchange of genetic information between the pair of homologous chromosomes allows genetic variation among the population. ![]() If the chromosomal reduction process is not maintained, it could cause genetic abnormality in the child. When the sex cells fuse to form a zygote, the usual chromosome number of 46 chromosomes is restored in the new individual. To maintain the chromosome number generation after generation, the gametes formed from the meiotic division should contain half the number of chromosomes (23 chromosomes) as the parent cell.
