Answer:
The answer is Natural selection
<span>Meiosis is the cell division process that produces gametes (sperm and egg).
</span><span>It products half the number of chromosomes (23 - a haploid cell). When the gametes fuse together, they produce 46 chromosomes.
</span>
Hope this helps :)
(See figure below, where meiosis I begins with a diploid (2n = 4<span>) cell and ends with </span>two<span> haploid (n = </span>2<span>) cells.) In humans (2n = </span>46<span>), who have 23 pairs of chromosomes, the number of chromosomes is reduced by half at the end of meiosis I (n = 23).</span>
