Question

Which of the following is suitable for experiment on linkage ?

• A. aaBB $\times$ aaBB
• B. AABB $\times$ aabb
• C. AaBb $\times$ AaBb
• D. AAbb $\times$ AaBB

Answer 1

Answer: (B)

AABB $\times$ aabb

AABB x aabb is suitable for the experiment on the linkage. Linkage is the tendency for certain genes tend to be inherited together because they are on the same chromosome. Thus, parental combinations of characters are found more frequently in offspring than non-parental.

So, the correct answer is 'AABB × aabb'.
