Reproduction is the process by which new individual organisms are produced. Reproduction is a fundamental feature of all known life; each individual organism exists as the result of reproduction.

San'Shyuum ReproductionEdit

San'Shyuum have both male and female genders and give live birth. Their reproduction is a strictly controlled affair though, considering the extremely limited gene pool, and individuals with undesirable genomes are added to the Roll of Celibates and forbidden to produce offspring to prevent negative recessive traits from entering the San'Shyuum gene pool. This does not prevent them from engaging in intercourse, however, and concubines are kept by high-ranking Prophets for this purpose. Illegal reproduction can result in the death of the unwanted child and sterilization of the guilty parent, even for a Hierarch.[1]

During sexual intercourse, San'Shyuum tend to wrap their necks around each other as a form of sexual foreplay.[2] Similar to humans, the San'Shyuum are experience heavy breathing during such intimate moments.[3]

Huragok ReproductionEdit

Huragok lack genders as understood by other species. Instead, two or even three Huragok work in unison to create a child, born of equal parts of the parents, sharing some memories and personality traits. Although it is not true biological reproduction because Huragok are artificial in origin and rely on microscopic nano-machinery to create new individuals, it still results in the creation of a new life.[4]

Unggoy ReproductionEdit

Unggoy have two genders, male and female, and they reproduce prodigiously, bearing a huge number of progeny.[4]

Yanme'e ReproductionEdit

Yanme'e somehow use Queens and Hives to reproduce.[5]

Sangheili ReproductionEdit

H2A CinematicRender Thel 'Vadam-Naked3

Cinematic render of the "Naked Arbiter" that would be the basis for all Sangheili models in Halo 2: Anniversary.

Sangheili have no external reproductive organs.[6] Female Sangheili are oviparous meaning they do not give live birth.[7]

Lekgolo ReproductionEdit

Each Mgalekgolo is formed from a single colony splitting in two, their dorsal spikes being the remnants of the last connections between the two parts of the colony.[citation needed]

Flood ReproductionEdit

The Flood reproduce similar to that of a flower spreading pollen. The carrier forms produce spores and infection forms. Once a Carrier form reaches the end of its lifespan, it explodes releasing the spores and infection forms. These infection forms go on to spread further flood infection, ultimately creating more Carrier forms to repeat the cycle. Furthermore, there are Flood Hives that produce spores and Flood growth pods along its biomass walls. These growth pods incubate new Flood life. They explode upon hatching, releasing more infection forms.
