Question

If Plant A with yellow flower (dominant trait) is crossed with Plant B white flower (recessive trait), what is the percentage of the offspring having a yellow flower? Plant A: YY Plant B: yy

Answer 1

Answer:

100%

Explanation:

Yellow flower color (Y) is dominant over white flower color (y). Plant A is YY while plant B is yy:

       YY    x    yy

  Yy    Yy    Yy    Yy

All the offspring would have Yy genotype and since Y is dominant over y, all of them will have yellow flower color as opposed to while.

Hence, the percentage of the offspring that will have a yellow flower would be 100%.
