Father: AaBb
Mother: aabb

Basically, I need to know what the offsprings would be, and their ratios.

I am not trying to be another one of those kids who go on here so that others can do their homework for them. I have literally been here for over 1 hour trying to solve this problem. It's confusing me.
Kenny, thats exactly what I was thinking but then I kept telling myself that I am probably wrong. I will wait and see what others have to say so that I will know if you are right or wrong.
Sooo Kenny is saying I should use 4 ab's and Zach is saying I should use 1 ab? Which one is it?
