In the hexaploid wheat, the haploid ( $n$ ) and basic $(x)$ numbers of chromosomes are:
In the hexaploid wheat, the haploid ( $n$ ) and basic $(x)$ numbers of chromosomes are:
$n=21$ and $x=21$
$n=21$ and $x=14$
$n=21$ and $x=7$
$n=7$ and $x=21$.
Solution
The basic number $(x)$ of chromosomes in wheat is 7 so, $6 x=2 x=42$ and $n$ $=21$
