I spoke briefly about this in the Discord but wanted to speak here; as of posting this, the only person who could overrule the image I have would be
@Wes - for that reason I'm going to be very concise about this so that in the future we can recall this post for any further documentation and changes. In a way, this app will serve two purposes.
I believe the Super Chromosome waters down at the Half/Quarter Mark.
This means that it is possible for a Quarter ID-SOL to have a female daughter
as long as their partner is not any part ID-SOL. I think this is fair and fits my view that Nepleslia had a few generations of genuine gender imbalance because of just how many ID-SOL were produced nearly a century ago in IC-history. Obviously they've been produced since in smaller number but this does not constitute numbers great enough to impact the population.
Now, it should be VERY rare for them to have daughters such as maybe a 10% chance of having a daughter. Obviously the ID-SOL blood has diluted in these to be at less than a quarter of their blood. I think it also partially helps explain the increased size of most females currently entering the RP; they'd be born from Quarter ID-SOLs by the current generation if not lesser. Obviously the strong genetics from ID-SOL remain even when dilluted (I would like to personally believe that it shows in women due to involving some use of the now-extinct giant women's genetics in the creation of the ID-SOL), but they generally shouldn't be anything that allows them to pop out someone who could be classified as an ID-SOL.
My logic for the Half/Quarter mark is due to the fact that this is the mark generally when we stop mentioning someone is an ID-SOL; specifically Quarter is when it becomes an afterthought and the person is generally marked instead as a Nepleslian.
So in that regard; being the child of a Quarter ID-SOL and being a female seems perfectly fine to me. It would be a definite subject of debate if they had tons of sisters or were to be somehow a Quarter ID-SOL themselves, but that doesn't seem to be the case here.
TLDR: Fine in my eyes.
