Answer 4

Since it is recessive, it will be out ruled unless two recessive genes combine. If one is AA and the other is Aa the There will be AA, AA, Aa, Aa. AA is dominate, therefore Aa can have the possibility of either trait. So, if there are six, the answer is definitley NOT A or B.

Answer 5

c

Answer 6

I think it's a 75-25% because AA and Aa. 3 capital, 1 lower case. So, yes, C would be the best option.
