If this was a donated egg, then Mom would be the "oven" but it wouldn't be her "bun" genetically speaking, right?
But, I wonder if the genes of the surrogate mother don't somehow "seep" into the fetus. I mean, she has to have some sort of hookup to feed it, right?
I suppose the scientists say "no" but it seems odd that it doesn't.
The genetics of getting sperm from an artificial insemination of a close relative are the exact same as getting pregnant through sex with said person. Though most of the time, the sperm bank gives kids problems by not realizing the donor and the recipient are closely related. A person who donates many times also unwittingly creates a place where people are know half-siblings without realizing it.
