Pretend human eye color is determined by a single gene, with brown eyes (b) being dominant over blue (b). a brown-eyed man marries a blue-eyed woman, and they have three children. two of the children are brown-eyed, and one is blue-eyed. what is the probability their fourth child will have the genotype bb? (2 points)
a. 100%
b. 75%
c. 50%
d. 25%

75

Explanation:

since the woman has 2 bb ur automatically gonna have one b, though you dont know weather the man received BB or Bb so basically if he got BB their is a 100 percent chance his children got Bb but if he has Bb his children only have a 25 percent chance of getting it so ima say 50
