True or false human sperm and egg cells have 23 chromosomes?

True. Sperm and egg cells are gametes, and thus are necessarily haploid. These haploid gametes were created through the process of meiosis. When the two fuse to create an embryo, the new embryo will then have 46 chromosomes, the full number for a human. The embryo will receive one copy of each chromosome from each parent. If sperm and egg cells were to have the full set of 46 chromosomes, with both copies of each chromosome from each parent, then when they fused the embryo would have 92 chromosomes total. And the progeny of that embryo would have an even higher number of chromosomes. Having haploid gametes is necessary to maintain the stability of the species.
