Sim Genetics

[Skarlath]

  Hi, I've been lurking this site for a while, reading and enjoying most of the threads and I thought maybe you can help me out?

I have this Sim family.

Charles (the husband), has brown eyes and black hair.

Judith (the wife), has green eyes and brown hair.

They have two children. The eldest has brown hair and brown eyes and the middle child has black hair and brown eyes.

I know that brown is a dominant eye color, but I can't help but want Judith's new baby to have green eyes.

So, this is my question.

Is there any way that I can change Charles's genetics to enable him to give green eyes to his future children while keeping his brown eyes?

If so, how?


Thanks so much!

You can do it with SimPE, and change his recessive eye color to green, but that still won't 100% guarantee the kid has green eyes. Rather than repeating all the instructions, check out this thread about fixing the Strangetown characters' DNA: http://www.moreawesomethanyou.com/smf/index.php/topic,1423.0.html.  You'll find all the info you need in that thread to use SimPE to change any sim's genetics.

Hehe, jsalemi beat me to the punch.  But yes, this is what I've done and although it doesn't guarantee green eyes, there's a better chance than when Charles would have both dominant and recessive brown eyes genes.




edit to fix spelling mistakes.

Wow, that was quick!

Thanks, I appreciate it!

Don't forget to save pre birth as well so if the bub shows up with the wrong coloured eyes, you can rinse and repeat until you get what you want.

That's precisely what I had been doing before to see if the eye color would change, but alas it didn't. Hehe.

Presuming Judith also has green eyes recessive, that should give a much better chance if you give Charles recessive green eyes as well. 

I am always messing about with DNA in my game.  I make sure that all townies and NPC's have different recessive genes and I always alter all the pre-made Maxis Sims, because their DNA is totally up the creek.  I mess about with eye colours too, being from the UK where almost 100% of the population has blue eyes.

It worked! The bouncin' baby boy has green eyes and brown hair.

I dispute this - being from the UK too - I have green eyes and my daughter has brown eyes.  My sister has brown eyes, most of my neighbours have brown eyes  - it is blue eyes that are  in short supply around here!

If one of your sim parents is homozygous for a dominant gene (brown), the chance of getting green eyes on your spawn is zilch, although it may manifest in grandchildren.

Or Great- grandchildren

Yea... "better chance" being that anything is greater than zero.
