Mating

Mating is the pairing of organisms for sexual reproduction, involving the transfer or exchange of gametes or reproductive material.

Gamete: A reproductive cell that fuses with another gamete during sexual reproduction. Mating enables gametes to meet or be transferred between organisms.
Sexual reproduction: Reproduction involving the combination of genetic material from reproductive cells, usually from two parents. Mating is a means of bringing organisms together within this broader reproductive mode.
Artificial insemination: The deliberate introduction of sperm into a female reproductive tract without copulation. It achieves sperm transfer while bypassing mating between the organisms.
Sexual selection: A form of natural selection driven by differences in access to mates or fertilization. Competition and mate choice can favor traits that improve mating success.
Asexual reproduction: Reproduction that produces offspring without the fusion of gametes. It generates offspring without mating between organisms.
Internal fertilization: Fertilization in which sperm meets an egg inside an organism’s body. Many mating systems transfer sperm into a partner before fertilization.
Sperm: A male reproductive cell that can fertilize an egg. In many species, mating transfers sperm to a partner or shared site.
Selective breeding: The planned reproduction of organisms with chosen traits to influence later generations. Breeding programs control which individuals mate to shape inherited traits.
Mate choice: The selection of reproductive partners based on particular traits or signals. Partner preferences influence which individuals mate and reproduce.
Parthenogenesis: Development of an embryo from an unfertilized egg. Some organisms reproduce through unfertilized eggs rather than mating and fertilization.
