Answer:
Brown eyes = 0.5
Blue eyes = 0.5
Explanation:
Given, B ( brown eyes ) is dominant over b ( blue/light eyes ). So,
BB = Brown
Bb = Brown
bb = blue/light
Mr. O'Ryan = blue eyes = bb
Mrs. O'Ryan = heterozygous brown eyes = Bb
Their children: Bb X bb :
B b
b Bb bb
b Bb bb
Half of the children will have Bb genotype and brown eyes, other half will have bb genotype and blue eyes. Hence, Kellan O'Ryan has 0.5 probability of blue eyes and 0.5 probability of brown eyes.
