Vedclass · Answer

(D) The basic chromosome number of wheat is $x = 7$. Hexaploid wheat $(6x)$ contains $42$ chromosomes $(6 	imes 7 = 42)$. $1$. Monosomic: One chromosome is missing from the diploid set $(2n-1)$. Since $2n = 42$, monosomic is $42 - 1 = 41$. $2$. Haploid: Half the number of chromosomes in the somatic cell $(n)$. Here, $n = 42 / 2 = 21$. $3$. Nullisomic: One entire pair of chromosomes is missing $(2n-2)$. Here, $42 - 2 = 40$. $4$. Trisomic: One extra chromosome is present in the diploid set $(2n+1)$. Here, $42 + 1 = 43$. Thus, the correct sequence is $41, 21, 40, 43$.
