Detailed explanation-1: -These sex cells are also called reproductive cells or gametes. Sperm cells are produced in men’s testicles and egg cells are produced in women’s ovaries.
Detailed explanation-2: -In the human reproductive process, two kinds of sex cells, or gametes (GAH-meetz), are involved. The male gamete, or sperm, and the female gamete, the egg or ovum, meet in the female’s reproductive system. When sperm fertilizes (meets) an egg, this fertilized egg is called a zygote (ZYE-goat).
Detailed explanation-3: -In animals, female gametes are called ova or egg cells, and male gametes are called sperm. Ova and sperm are haploid cells, with each cell carrying only one copy of each chromosome. During fertilization, a sperm and ovum unite to form a new diploid organism.
Detailed explanation-4: -We have 23 pairs each with 50/50 probabilities. That works out to 223 possible combinations of gametes from one human individual.
