Solution
The halving of chromosomes during gamete formation.
Explanation:
There are always half as many chromosomes in gametes as there are in an individual. As a result, chromosomes are cut in half just before gamete formation. The normal chromosome number (half from each gamete) is restored once the male gamete fuses with the female gamete.
