Answer:
eight (8)
Explanation:
A phenotypic ratio of 9:3:3:1 is predicted from a cross of AaBb x AaBb (i.e., in a dihybrid cross). In this case, the expected phenotypic ratio is equal to:
A_B_ (9:3:3:1) =71.43 >> 71 both dominant phenotypes
aaB_ (9:3:3:1) = 23.81 >> 24 one dominant phenotype
A_bb (9:3:3:1) = 23.81 >> 24 one dominant phenotype
aabb (9:3:3:1) = 7.93 >> 8 both recessive phenotypes
Expected phenotipic ratio (9:3:3:1) = 71 + 24 + 24 + 8 = 127
Answer: 8
Explanation: 127 divided by 16 which is how many boxes you have in your punnet square is 7.9 so just round and it gives you 8!
