Because one's ovaries don't just produce eggs, they do important hormonal stuff.

My brain just goes "spring. wait, they don't spring" when you say hormonal stuff.

Hormones do other things!

I know, but "hormonal" is like a euphemism for "springing really bad".

It's a euphemism for "horny teenagers"--uh, adolescents--for us.

So same deal.

Less with the babies thing.

Weird. I bet your porn is different.

Your porn has babies in it?

No, it has people talking about getting pregnant though.

Yeah we have less of that.

She continues corresponding with theologians. Would it help resolve the hereditary pollution thing to call in any geneticists.

Pollution isn't precisely genetic!

Oh?

They send her more impenetrable papers.

Lovely. Can she persuade any of them to supplement with penetrable summaries?

Sure! There isn't a pollution gene, but there's no way for a red to conceive a baby with decontaminated material and a sufficiently contaminated living thing self-maintains pollution rather than eventually clearing it.

So, say, if someone were perverse enough to analyze a red's genome completely, and then copy half that sequence of alleles into a clean gamete, you could have a baby that was the genetic child of a red without being red themself?

Yes, assuming caste inheritance law agreed.

It seems like it would be horribly unethical to make someone who wasn't inherently unclean live as a red.

It would be horribly unethical to make an embryo that would inherit red caste and then try to install them somewhere else!

Okay, true. Anyway, this suggests that if the mass in a red's body was replaced sufficiently fast that should work. Is she wrong and if so why.

It would have to be very fast. Pollution transmits really quickly. But yeah that sounds right.

One of the kinds of magic has as a feature the fact that it is easier to do things instantaneously with it than not!

Cool!

She will write up proposals for an exact procedure and they can accept reject or edit them?
