Brown eyes is dominant to light eyes. Mr. O'Ryan has blue (light) eyes. Mrs. O'Ryan is heterozygous for brown eyes. What are the eye color possibilities of their son, Kellan O'Ryan? *Use letter B

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.

an organism's phenotype is the  form of a trait  that it  displays. for  flowercolor, a pea  plant  can  display  a phenotype of purple or white flowers. an organism's  genotype  is the alleles of a gene it contains. based on his data, mendel concluded that a phenotype can be  determined  by more than one  genotype.
