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
