My Sim has black hair and her future husband has red hair. But my Sim's dad has blonde hair, and her future husband's dad does, too. Does that mean they could have a blonde baby? Sparrowsong 04:44, March 20, 2010 (UTC)
I think it could be possible. —Preceding unsigned comment added by DavidMC123 (talk • contribs)
Yeah, actually, it's even likelier that their children will have blonde hair rather than red. If your sim's dad is a pure blonde (that is, he has two blonde alleles), then your sim has one black allele and one blonde allele. Similarly, your sim's future husband has one red allele and one blonde allele if his dad was a pure blonde. So, there's a 50% chance that their children will have black hair (because black is dominant and will always be shown rather than the recessive allele). In 25% of the cases the child will be pure blonde and in the remaining cases the game will decide randomly if they're blonde or red-haired (because both red and blonde are recessive traits). All in all, there is a 37,5% chance that they'll have blonde children. Crusoe704 22:46, March 27, 2010 (UTC)
