well..heteorygous brown eyes woman, and blue eyes man..and allele for brown eye is dominant..so if we assume tht brown allele is B, and blue allele is b..then, the woman is Bb and the man is bb
after we cross the Bb with bb..the offspring are Bb Bb bb bb...ratio is 1:1...so that means..for blue eyes (bb), probability is 1 in 2 (50%) that is A
hope you understand.
