Okay thats what I thought cause on My biology test I put 100% and he marked it as wrong and I kept doing the punnet square driving myself crazy trying to figure out how I was wrong, but now i'm going to bring it to his attention tomorrow.
Thanks everyone!

I think it is 100% bc if you make the Punnet Square, then there is no other option... Mom's "a" matches with Dad's "a" in all four cases.

E) 100%
If they're both recessive homozygous, there is no other possibility than homozygous recessive.
