Kindly do not put words in my mouth Gavin. I never made a claim that a FAQ was a reliable secondary source. I added three references: two 3rd party magazine articles, and a link to an interview with the original creator of the Githyanki. Collectively they're enough to nuke the notability tag you slapped on the article.
Egg incubation is the process by which an egg, of oviparous (egg-laying) animals, develops an embryo within the egg, after the egg's formation and ovipositional release. Egg incubation is done under favorable environmental conditions, possibly by brooding and hatching the egg.
These organisms often do not possess different sexes, and they are capable of "splitting" themselves into two or more copies of themselves. Most plants have the ability to reproduce asexually and the ant species Mycocepurus smithii is thought to reproduce entirely by asexual means.
During physiological polyspermy, the egg accepts multiple sperms but only allows one sperm to fuse its nucleus with the egg's nucleus. Unlike physiological polyspermy, monospermic fertilization (described above) deals with the analysis of the egg calcium waves, as this is the typical reproduction process in all species.
The few animals that do not return to their natal region and stray to other places to reproduce will provide the species with a variety of different locations of reproduction, so if the original natal locations have changed, the species will have expanded to more places and will ultimately increase the species' survival chances.

Pregnant male seahorse. Male pregnancy is the incubation of one or more embryos or fetuses by organisms of the male sex in some species. Most species that reproduce by sexual reproduction are heterogamous—females producing larger gametes and males producing smaller gametes ().
External fertilization is a mode of reproduction in which a male organism's sperm fertilizes a female organism's egg outside of the female's body. [1] It is contrasted with internal fertilization, in which sperm are introduced via insemination and then combine with an egg inside the body of a female organism.
