Copulation

 

(1) The union of two individuals in sexual intercourse.

(2) The process of the syngamy of two sex cells (gametes). Copulation is usually understood to mean the syngamy of sex cells that are externally almost or completely indistinguishable. If the male gamete differs sharply from the female, the process of their syngamy is called fertilization.
