Question

In a test cross for two characteristics (dihybrid cross), can the predicted frequency of recombinant offspring be 60%?

a) Yes, because recombination is independent of the genes being tested.
b) No, because the predicted frequency of recombinant offspring is always 50%.

Answer 1

In a dihybrid cross, the predicted frequency of recombinant offspring can be higher than 50%, depending on the distance between the genes being tested.

Step-by-step explanation:

In a dihybrid cross, the predicted frequency of recombinant offspring can be higher than 50%. It can range from 0% to 100% depending on the distance between the genes being tested. If the genes are located very far from each other, the predicted frequency of recombinant offspring can be as high as 100%. However, if the genes are located very close together, the predicted frequency will be lower. A predicted frequency of 60% is possible if the genes are located at an intermediate distance from each other.
