Extended data:

Mating is the behavior that fertilized animals fuse germ cells (sperm and eggs) in vivo through the combination of sexual organs. Mating is an animal instinct. When animals are sexually mature, they will enter estrus regularly. During estrus, both male and female animals will have a series of physical changes. Different animals have different mating time, regardless of size. After mating, the crystallization of love between animals was born.

It can be divided into five types: hybridization, self-crossing, test crossing, positive back crossing and back crossing.

The mating activity of birds and fish can be called mating, and the mating of fish is also called seed biting. Male sperm will enter the female body and fertilize the egg cells. However, if the fertilization process takes place in vitro or without sexual intercourse, it is no longer mating, such as fish (both sexes discharge their germ cells into water to complete fertilization) or artificial insemination.
