complete the punnett square, then interpret the results. (brown eyes are dominant; blue eyes are recessive)

b

b

brown eyes: out of or %
blue eyes: out of or %

This would be difficult to specify for you because you did not provide the genotype of the other parent. However, there are limitations to the possible combinations, so I will do each to help you out.

1st possibility:

    B      B

B  BB  BB

b  Bb   Bb

Brown eyes: 4 out of 4 or 100%

Blue eyes:    0 out of 4 or 0%.

2nd possibility:

    B      b

B  BB  Bb

b  Bb   bb

Brown eyes: 3 out of 4 or 75%

Blue eyes:    1 out of 4 or 25%.

3rd possibility:

    b      b

B  Bb  Bb

b  bb   bb

Brown eyes: 2 out of 4 or 50%

Blue eyes:    2 out of 4 or 50%.

As long as there is a capital letter in the genotype, the dominant trait will come out. So if the combination is Bb or BB, then BROWN in this case will come out. The only time BLUE eyes will come out is if has two recessives in its genotype or bb.
