  • In a F1 dihybrid cross (WwGg x WwGg) where W = round, w = wrinkled, G = yellow and g = green, what is the probability of obtaining an individual that is wrinkled and green? (CG ADA 2023)

    Question: In a F1 dihybrid cross (WwGg x WwGg) where W = round, w = wrinkled, G = yellow and g = green, what is the probability of obtaining an individual that is wrinkled and green? (CG ADA 2023)

    Options:

    1/16
    1/2
    1/8
    9/16

    ✅Explanation:A dihybrid cross results in a phenotypic ratio of 9:3:3:1, which means 9 out of 16 will be round and yellow, 3 out of 16 round and green, 3 out of 16 wrinkled and yellow and 1 out of 16 wrinkled and green. Therefore, the probability of obtaining wrinkled green offspring is 1/16.
