Reproductive Anomalies

Orcs
The Orc sex chromosomes have a dominant gene accelerating the gestation period for all orcs. The gene's behavior has baffled scholars, and has proven a dominant gene when orcs mate with other species.

Gestation is between 4-7 days. Other than the rapid timeline, development is consistent with that of other humanoids, relying on similar hormone changes in the female bearing the offspring.
