Strange Genetics

[lugia61617]

It's another thread form me, guys!

OK, so this time I want to discuss the odd workings of genetics. Mainly because of my VERY recent experience;

An alien hybrid sim married a japanese-like sim, and they had two children. What was odd is that one of them had a custom skintone (the see-through one that can be found on here) and yet the parent families have NEVER had a member with that skintone. I can't help but wonder what's next, a steampunk baby with seethrough parents?

So have you ever had something like this happen like that? I wanna hear your strange genetic stories.

Ooo, strange!

In my legacy on my old computer ((R.I.P Tom)) I was lucky enough to survive to twenty Generations. The founding Sim had bright orange hair, but after she married a Sim with black hair, all the children, even the ones in the later generations, had Black hair. But the very last child to be born to that family had bright orange hair, even though both parents had black hair. About time!

I have one very dark skintone that I only recently geneticized. Well I created a sim with that dark skintone and she had a few babies with a man of skintone #3, but all of her babies were her skintone. Those kids grow up, and so the oldest of them gets married to a man with skintone #4. She ends up having two kids with him and both kids come out skintone #3, which looks a little odd with the father being #4 and the mother being even darker than that.

In another case of strange genetics...I created a family with the father having a unique custom hair (was not properly binned but it spanned several age levels); in the family there was also the mother and a daughter. After I killed the father off, I never used that hair again and considered deleting it, but I ended up forgetting about it entirely. When the first great-grandson of that man came along I had to age up the toddler to an adult so that he could use the plastic surgery machine (he had some alien genes and inherited huge eyes that I had to fix). And I was surprised to see that he had the same exact custom hair that his great-grandfather had been created with.

It might have been that the custom skintone had a genetic value inbetween the parents' skintones.

As for me, my genetic weirdness tends to come from the fact that I sometimes forget that I set recessives in CAS. I made two sims (one male, one female), both with black hair, and they had three children. Because I dislike having generation upon generation of the same family with the same hair colour, I had the youngest son marry a red-haired woman. After a few sim-days the woman gets pregnant and gives birth...to a blonde-haired girl. It took me a while to figure out that I'd given the black haired male a recessive blonde gene in CAS -- he'd then passed that blonde gene on to his youngest son, who then gave it to his two daughters.

Another strange genetic event was when I was playing with aliens. I had twin aliens, one boy and one girl, both with black hair, born in to my game. I had the boy marry another playable (who also had black hair), and they had four children: two male, two female, two with alien skin, two with normal skin, three black-haired...and one red-head. Poor kid looked so out of place in a sea of black-haired sims. The girl, on the other hand, married a townie and ended up having twins. I had to re-load the birth numerous times because I did not understand why she was having kids born with brown eyes when no one in her family had ever had them -- turns out the kids that were getting 'brown' eyes were getting the alien eyes. I had no idea about getting a fix for alien eyes not showing on non-alien skin, so I kept reloading until neither kid had 'brown' eyes.

How do you set recessives in CAS?

How do you set recessives in CAS?
You can do it by "rolling the pacifier" I think. If you make a male and a female adult then make their children in CAS using the "make baby" option, I think that the children will then have recessive genes (if applicable).

Other than that you can also edit your sims in SimPE to give them recessive genes. I tried to find a tutorial to link, but couldn't find one. I'm sure there are some out there though!

**EDIT** Have a look at the link that Mootilda posts in this thread (http://forums.modthesims.info/showthread.php?goto=newpost&t=403642), that explains it but isn't hugely clear about how to do it if you're not already used to SimPE..... And it's quite a long read!

Yes, that's how I personally set recessive genes, and from experience I can safely say that it DOES work: I made a couple in CAS each with a recessive hair and eye colour, and although all their children showed the dominant traits (black and brown hair, can't remember which eyes I used now), by the time I got to generation 5 I was finding blonde kids :)
I'm still thinking the red hair has been lost somewhere down the line though, as I gave one parent that as the recessive gene, and have NEVER seen that come out...
While I have SimPE I'm not going to dig through the genetics - more fun just to see what comes up!

Cool :-) I've never really tried it - though I often "roll the pacifier" to make teens/children/toddlers in CAS I don't usually play them long enough to see what genes they pass on to their offspring! I never look at my sims genetics in SimPe, it really is more fun to just wait and see what happens!

So how does it work exactly with rolling the pacifier to make adults? You start with 2 adults, I assume, then make them have a kid, which you then age up to adult? Can you edit the sim you've made (not changing hair/eye/skin colour, but say personality, or facial features?), or if you edit it will it lose the recessive genes?

As far as I can tell, editing the personality doesn't make a difference to the genetics, however I've been reluctant to edit facial features so I can't comment on them. When I'm rolling for my new sim (yes, you assumed right in that I make the kid then age up to adult) I'll go with a set of features that either looks halfway decent or keeping a certain feature that I want. As an example, say I WANT the "dad's" big nose, I'll keep a kid that inherits it and ignore those that don't.
I'm a little wary regarding hairstyles as I'm unsure whether tampering with them alters the genetics, even if I don't change the colour. I usually take what I'm given then edit using the mirror in-game.

As a FYI, when rolling the pacifier for the child you can set the age shown, so it's possible to see all ages of the resulting sim before you save them. Very useful if you want to age up to adult or are just interested on how the cute (or not-so-cute) kid will turn out later in life. :)

Yep -- start with two adults with whatever genes you want, make them have as many children as you want and age up to adult. You can freely change everything except hair and eye colour (and maybe skin, but I don't tend to touch that) as, like you said, changing those will lose your recessives.

I used this method to create all of the starting families in my prosperity challenge, Angelos Town (http://eien-herrison.livejournal.com/74051.html) -- it's most noticable in the Eddleman family as the mother has blonde hair/light blue eyes while her daughter has brown hair/green eyes from her DNA donor 'father' in CAS. The daughter does have blonde hair/light blue eyes recessive, but the blonde hair has yet to show up largely due to her marrying and having children with a black-haired man.

Edit: Facial structure I assume can be changed reasonably well (I tend to make the parents with the structure I want and don't bother fiddling around with the child), but I've definitely changed the hairstyle with no issues.

Thank you, I'll have to learn a bit more about SimPE to understand some of it but I had no clue about the pacifier. Cheers!

[lauratje86]

You're welcome Bellasaurus - as you can probably tell from all my questions I wasn't entirely sure how it worked either!

Thanks Selly_2009 and katya_stevens for all the info, I'm off to start up my game and try it out! :-)

once i made a couple in CAS, black haired man and brown haired woman, and i made them 2 brown haored kids (without using the pacifier) who both had brown haired spouses, but still, about half of the grandchildren had black hair!
