hard · MCQ · Q-D11538
In a dihybrid cross involving two linked genes, the frequency of recombinant types is generally:
- A.Equal to the frequency of parental types
- B.Always 50%
- C.Significantly less than 50%Correct answer
- D.Greater than 50%
Solution
Linked genes tend to stay together during inheritance. Consequently, parental combinations occur with much higher frequency than recombinants, making the recombinant frequency less than 50%.
