In the hexaploid wheat, the haploid (

n

) and basic

(x)

numbers of chromosomes are:

Options

A $n=21$ and $x=21$
B $n=21$ and $x=14$
C $n=21$ and $x=7$
D $n=7$ and $x=21$ .

Correct answer

C. $n=21$ and $x=7$

Step-by-step solution

The basic number

(x)

of chromosomes in wheat is 7 so,

6 x=2 x=42

and

n

=21

Related Theory Triticum aestivum is known that hexaploid common wheat has stronger adaptability to many stressful environments than its tetraploid wheat progenitor.
