Answer 10

This is the only way you could get what you see in the chart:



Aa and AA show the dominant trait and aa is recessive.

You can try other combinations on your own: AA and AA, AA and Aa, aa and aa. As you will see, none of them will produce both offspring that show the dominant trait AND offspring that show the recessive trait.
