Answer :
Answer:
Meiosis
Explanation:
In human, there are somatic cells and germ cells. Sperm and egg are called as germ cells or gametes which can be found in gonads (testis and ovarium).
In beginning, the gametes are diploid or have 46 chromosome (23 pairs). Diploid means contain two sets of chromosome.
To maintain the homestatic in terms of quantity of chromosome, each gamete, either sperm or egg must be haploid or only have one set chromosome (23 chromosome).
To make it happen, each gametes undergo a process named spermatogenesis and oogenesis. After the gametes (diploid) are duplicated through mitosis, the gamete will be divided through meiosis for producing gametes (haploid). Meiosis is a type of division cell that reduce the number of chromosome, from diploid to haploid.
As the gametes, sperm and egg (haploid) fuse together in sexual reproduction, it can back into the double chromosome (diploid).
