Reproduction is the production of offspring by a sexual process or asexual process.
The vast majority of animal species (including humans) reproduce sexually but some
reproduce asexually. In other words, Reproduction in the vast majority of animals is only possible when a male animal and a female animal come together to have sex. This is also known as breeding or mating.
Animals that reproduce sexually, breed with members of the
opposite sex due to a desire for sexual pleasure, love, and the need to propagate the next generation.
Heterosexual is the only kind of sex that can lead to
sexual reproduction.
