Barefoot, pregnant, and at the mercy of InSIM: testing genetics

Recently, I tried fiddling with the recessive genetics in Strangetown, using SimPE, since [personal profile] madame_ugly was nice enough to explain it all to me a while back. The return of InSIM made it easy to test them out, so that's just what I did, using my favourite approach - the HANDS ON method.






Yes? Is there something you all wanted to tell me?




That's right, my friends. You got knocked up via InSIM, and you'll have no idea who the other parent is... oh, wait, yes you will. The green ones are Johnny's.




Ophelia: Okay, it's time to clean up these babies, guys! Get to work and start picking them up.

I love how the children of Ripp and Ophelia have such a wide range of skintones, instead of just ending up averaged out (that seems to always happen for me).

Even with all of those babies, I didn't get any kids from Johnny with red hair, so I'm not sure if I correctly changed his genetics. I'll have to test it out again. All of these kids had blond hair, so Ripp's recessive genetics are definitely working (I had some grey eyes too).

It's so nice to have InSIM back. I'm not sure if my sims agree, though.

Jumping into the fray and dusting off my (limited) knowledge of real genetics. There is a grid you can use (basically a box split into four smaller boxes)That shows how dominate and recessive genes will pair up (taking one gene for each from each parent).
Taking blonde/red and blonde/red and putting them in the square you come up with the squares looking like this:
1 BB 2 BR
3 BR 4 RR

If blonde comes through more dominate then red then your children have a 75% chance of being blonde. 25% chance of having a true redhead. There is a 50% chance that any offspring will be carrying the gene for red hair and a 25% chance of an offspring being totally blonde.

I hope that all made sense, I just came in from mowing the lawn. :)
Also, this is for real biology, I have no idea what works for sims.
This concludes our biology lesson for today. Memorize this...there will be a test. ;D
