Detailed explanation-1: -The formation of sex cells is a central part of human reproduction: In fertilization, an egg cell and a sperm cell combine. 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: -A gamete is a reproductive cell of an animal or plant. 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-3: -The male reproductive cell is known as sperm and the female reproductive cell is known as ovum. The collective term for the reproductive cell is gamete.

Detailed explanation-4: -During fertilization, male and female gametes fuse, producing a diploid (i.e., containing paired chromosomes) zygote.

Detailed explanation-5: -Oogenesis is the process of female gamete formation in animals. This process involves meiosis (including meiotic recombination) occurring in the diploid primary oocyte to produce the haploid ovum. Spermatogenesis is the process of male gamete formation in animals.
