Brown eye-color is dominant while the blue-eye color is recessive. Therefore, the homozygous for brown color is BB and the homozygous for brown color is bb. Thus, the heterozygous will be Bb (brown color). Since James has blue colored eyes a child of Jenna (brown color) and bill (blue color) then it means Jenna is heterozygous (Bb). Jenna is described as being a carrier of the allele for blue eyes.
