In the hexaploid wheat, find the haploid(n) and basic (x) no. of chromosomes.
a). n=21 and x=7
b). n=7 and x=21
c). n=21 and x=21
d). n=21 and x=14
and plz explain me how to find this...

Dear student

The correct option is a).

The basic number or monoploid number x of wheat is 7. The 6x (hexaploid) represents diploid (2n) condition. 

Therefore, 6x i.e 6 x 7 = 42 = 2n and n = 42/2 = 21.
