Question

Quizplus · Accepted Answer

The fusion of a haploid sperm cell and a haploid egg cell results in a diploid zygote with a total of 46 chromosomes (23 from the sperm and 23 from the egg). If the gametes had more or less than 23 chromosomes, the resulting zygote would also have an incorrect number of chromosomes, which could lead to developmental issues or even be incompatible with life.
