The possibility of hybrids between humans and other apes has been entertained since at least the medieval period; Saint Peter Damian (11th century) claimed to have been told of the offspring of a human woman who had mated with an ape, [3] and so did Antonio Zucchelli, an Italian Franciscan capuchin friar who was a missionary in Africa from 1698 to 1702, [4] and Sir Edward Coke in "The ...
Domestic sheep reproduction. A cross-bred ewe suckles her lamb, which was the first of the 2008 spring lambing at a farm in Coventry, England. Domesticated sheep are herd animals that are bred for agricultural trade. A flock of sheep is mated by a single ram, which has either been chosen by a farmer or, in feral populations, has established ...
Hermaphrodite. A hermaphrodite (/ hərˈmæfrəˌdaɪt /) is a sexually reproducing organism that produces both male and female gametes. [1] Animal species in which individuals are either male or female are gonochoric, which is the opposite of hermaphroditic. [2] The individuals of many taxonomic groups of animals, primarily invertebrates, are ...
The domestic sheep (Ovis aries) is the only species of mammal except for humans which exhibits exclusive homosexual behavior. [1][2][3] "About 10% of rams (males) refuse to mate with ewes (females) but do readily mate with other rams." [2] Thirty percent of all rams demonstrate at least some homosexual behavior. [4]
A human–animal hybrid and animal–human hybrid is an organism that incorporates elements from both humans and non-human animals. Technically, in a human–animal hybrid, each cell has both human and non-human genetic material. It is in contrast to an individual where some cells are human and some are derived from a different organism, called ...

For reproduction by which offspring arise from a single organism, see Asexual reproduction. Inbreeding is the production of offspring from the mating or breeding of individuals or organisms that are closely related genetically. [1] By analogy, the term is used in human reproduction, but more commonly refers to the genetic disorders and other ...
Female and male sexual behaviour differ in many species. Often, males are more active in initiating mating, and bear the more conspicuous sexual ornamentation like antlers and colourful plumage. This is a result of anisogamy, where sperm are smaller and much less costly (energetically) to produce than eggs.
