Sexual reproduction

reproduction by having sexual intercourse, mating, fertilization and reproduction

Sexual reproduction is a union that results in increasing genetic diversity of the offspring. It is characterized by two processes: meiosis, involving the halving of the number of chromosomes; and fertilisation, involving the fusion of two gametes and the restoration of the original number of chromosomes. During meiosis, the chromosomes of each pair usually cross over to achieve genetic recombination.

Reproduction requiring the union of sex cells (gametes) which are themselves products of meiotic division. Each offspring has a unique genetic composition due to independent assortment of chromosomes during meiosis, recombination and union of gametes.
