Solution

The correct option is A Same chrormosome
As per linkage experiments carried out by Morgan, the two linked genes do not always segregate independently of each other and $F_{2}$ ratio deviated very significantly from 9:3:3:1 ratio (expected when two genes are independent). Hence, if linkage was known at the time of Mendel, he would riot have been able to explain law of independent assortment.
