Solution

The correct option is C n = 21 and x = 7
The monoploid (x) number is the number of chromosomes in a single set. Since the number of chromosomes in hexaploid wheat is 42, the monoploid number will be 426=7. The haploid (n) number is the number of chromosomes in a gamete. For hexaploid wheat, the gamete will be triploid. The haploid number of chromosomes =7×3=21.
