Solution

The correct option is C 10
The genes which are located on the same chromosome have the tendency to move together. These genes are always inherited together during the formation of the gamete. The number of linkage groups is always equal to the number of chromosomes. In the case of maize, there is 10 pairs of chromosomes present and so the number of linkages will be 10.
Thus, the correct answer is option B.
