ok this is kinda weird but i’ve been thinking about if two demigods had a kid, would there be a chance their kid could be immortal, or completely mortal? still a demigod, or more like a fourth of a god?
I mean on the surface, it seems like one of those things where the fractions would just keep dividing, but if you would think about them as alleles and dominant / recessive traits, for this example, lets use Mm (for mortality im clever) and the dominant M would be immortality and recessive m would be mortality. In the case of PJO, mortality would be incompletely dominant, showing signs of both parents (eg. being susceptible to both godly and mortal weapons; able to eat ambrosia, like their godly parent, but also able to eat regular food like their mortal parent). So if you have a god, they are completely immortal, MM, and their completely mortal partner, mm.
Now when you cross the two homozygous people, all the offspring would be Mm, a demigod, that is. Do a Punnett Square if you don’t believe me.
So you have a demigod (Mm) and they can produce offspring with a god (MM), another demigod (Mm), or a mortal (mm). If a demigod has children with a god, theoretically, their children would have 50% immortal, and a 50% chance of being a demigod. If a demigod has children with a mortal, their children theoretically have a 50% chance of being demigods, and a 50% chance of being completely mortal. Finally, if two demigods had children, their theoretical children have a 25% chance of being mortal, and 50% of being immortal, and a 25% chance of being mortal.
That doesn’t even scratch the surface though, I mean, what about mortals who have the power of Sight? Could immortality be a sex-linked trait? Does immortality work differently in demons and monsters, or is it the same? What about nymphs and naiads? Centaurs? Possibilities are endless with genetics guys get excit e d
It’s like Mendel meets mythology! Zeus would approve.
