.@BurningSims There's alien DNA and human DNA. When they woohoo together, the child gets a mix of the two that's approximately an even split. If you have a certain level of alien DNA within a Sim, that Sim will be considered an alien and have access to their powers. Alien DNA tends to be a bit more dominant between the two, so the first generation of offspring is nearly guaranteed to end up being alien before the gene pool begins to dilute. RT @BurningSims @SimGuruGraham How will Alien-Sim Hybrids work out? In TS2 their genetics could be a bit unpredictable but now powers are in the mix too :)
