Text Solution

Verified by Experts

The correct Answer is:
C
TH Morgan (1910) explained the lack of independent assortment in Drosophilia due to the linkage. When genes closely present adhere or link together in a group and transmitted as a single unit, the phenomenon is called linkage. It stops the process of independent assortment. Incomplete linkage is broken down due to the crossing over.
