Correcting the DNA of Strangetown premade characters
Dark Trepie:
Alien genetics has always confused me. Stella Terrano for example will always have alien children no matter who the father is (although they will inherit facial structure features from the father). But her children, when paired up with another human sim, will be normal human sims.
So, lets see if I understand this right.
Stella (alien/alien skintone/eyes, dark hair) + Human Male (the guy in my avatar - lightest/lightest skintone, light blue/light blue eyes, red hair) = Child (alien/lightest skintone, alien/light blue eyes, dark/red hair) With the dominate genes in bold. The child always seem to be an exact copy of Stella here, but with some of the father's facial features like I said before.
Now lets take the child and pair them up with a human. In my game the child of the two above was a girl and I paired her up with Alexander Goth.
Alien girl (alien/lightest skintone, alien/light blue eyes, dark/red hair) + Alexander (second lightest/second lightest skintone, brown/brown eyes, dark/dark hair) = A child that was almost an exact clone of Alexander.
So do the three human skintones and eyes overtake the one alien skintone and eyes in the third generation? Or is my assumption here completely off? ???
Also, do you think you can conjure up a list like this for Veronaville? Those poor pre-mades there seem to have a lot more DNA screwups than the ones in Strangetown. :)

You're almost right. It's not guaranteed that the human skintones will overtake in the third generation, but it's happened this time because of Alexander's boring homozygous DNA.
As far as I know, it's random which of the lines of DNA gets chosen to be passed on to the offspring. One line of DNA comes from each parent for each of the characteristics. However, for some reason in this particular case, the game decided that the child was going to have skintone 2. Because the child has a human skintone, it theoretically cannot have alien eyes. We know this doesn't always work because there have been some scary-looking sims born who had alien eyes in human skintones, or had alien-sized eyes with human-coloured pupils. But in theory, it shouldn't happen.
Now, as for why Alexander's other traits dominate, it's because he's homozygous dominant for eye colour and hair colour. If he had a recessive light blue eye gene, or a recessive red hair gene, you'd d have a lot more mixing in the children. So if you had instead had Alien girl (alien/lightest skintone, alien/light blue eyes, dark/red hair) + A boy (lightest/second lightest skintone, brown/light blue eyes, dark/red hair), you might well get a child who had red hair or light blue eyes. But because he has brown eyes and black hair which dominate over other colours, those characteristics are expressed in the offspring.
The offspring may well have a recessive light blue eye or red hair gene, though. And if paired up with another heterozygous sim, the fourth generation of kids could have the red hair or light blue eyes from their great-grandfather.

Er, maybe. I don't ever play Veronaville, because the premade story doesn't appeal to me. But I could probably poke around in SimPE one evening. Can't promise anything because I'm ill and I have several sim projects on the go already (getting anything done is subject to not being stoned out of my brain on strong painkillers).
I can certainly make a list of which sims are problematic, but working out what the DNA "should" be takes a fair bit longer :).
Dark Trepie:
Interesting. I'm pretty sure I understand it now. The next time I restart Pleasentview (which will be soon) I think I'll let all of the pre-mades get together and breed for a couple of generations before I throw my own sims into the mix so everyone isn't so homozygous. That way I'll get a little more variety in genetics in the neighborhood. And maybe Stella can have some grandchildren with alien features.

Heh, the first time I ever had a human sim and alien sim have a baby together in my game I was actually hoping this would happen. Because if two people from totally different species have a child together you would think the child would have traits from both species.
Motoki:
I don't really known if it's possible to have a sim with human skin and alien eyes without resorting to using custom content to do it. The alien eyes seem to be exclusively tied to the skintone and you can't select them in the CAS in debug mode unless you've also selected the alien skintone. And then if you change the alien skintone back to human, the eyes changed too.
However, I have extracted the texture for the Maxis alien eyes and made 'contact lenses' out of them so you could always do that.
Ancient Sim:
I've never understood why a game that had so much hype concerning the genetic angle saw fit to make such a mess of the genetics of the Sims that came with it. I remember at the beginning, before I had SimPE, waiting patiently in the hope that Dina or Nina would produce a kid with green skin ... now I know it isn't possible because their grandfather never had it in the first place, even though he was apparently the result of alien abduction. By the time I knew what to do to alter it, it was too late as I'd gone forward too many generations.
