Question about SimBlender tool in TS2?

So my Sim had an alien baby, and I’m planning on using her to continue the family (I’m doing a legacy-type thing, but with cheats because I’m lazy). Only thing is, I really hate their noses! So I found this mod which will let me edit them in CAS. I’m not sure if the changes I make will be passed on to her children, though, and I don’t want to have to keep fixing that hideous nose.

So, does anybody know if the Sim’s genetics are altered by changing their facial features?
