Green - 1/2 or 50%

Blue - 1/4 or 25%

Explanation:

First, let us carry out the cross between AaBB and Aabb using a Punnet's square. The result is as below:

AABb - 4/16

AaBb - 8/16

aaBb - 4/16

(See the Punnet's square analysis in the attached image).

<em>AABb genotype has 3 pigments, hence, would be hazel.</em>

<em>AaBb genotype has 2 pigments, hence, would be green.</em>

<em>aaBb has one pigment, hence, would be blue.</em>

Expected progeny:

<em>Hazel - 1/4 or 25%</em>

<em>Green - 1/2 or 50%</em>

<em>Blue - 1/4 or 25%</em>
