Thanks for telling me the traits Pam (
again, stupid me). She looks like a little inventor already, I'd like to see if you'll keep her hair short when she's older.
As for genetics in real life, it's a lot more complicated than the Sims
(deep breath, try not to make this too confusing). Mutations do occur, but they're usually harmful defects like Downs Syndrome and Cystic Fibrosis. If an unexpected trait like green eyes pops up, it's probably a recessive gene rather than mutation. For example, I myself am the only person in my entire family with green eyes. My mum and dad have brown and blue eyes respectively, so it's likely those eye colours were dominant genes and masked the green-eyed genes that were passed onto me. Or I'm a mutant, yay
. From the look of RubyLovesSims's article the genetics in
The Sims 2 were closer to real life than those in
The Sims 3, so although it's not completely accurate it's worth a read. Like I said, it's more complex in reality, which is why we get so much more variation in appearance, and also why I haven't learned a great deal about it in Human Bio beyond dominant and recessive genes
. Speaking of variation, if you believe we evolved from single-celled organisms, you have to believe that every variation between the members of our species originated as a mutation somewhere down the line! It took us billions of years though, those sort of mutations are really rare after all.
...Whew. At least this is still fresh in my mind from yesterday's Human Bio exam. Sorry for confusing anyone
