Vedclass · Answer

(B) Assertion $(A)$ is true because all somatic cells in an organism are derived from the zygote through repeated mitotic cell divisions. Since mitosis maintains the same chromosome number and genetic content,every cell contains the same genetic material as the original zygote.Reason $(R)$ is also true because the zygote is indeed formed by the fusion of haploid male and female gametes during fertilization.However,the reason $(R)$ explains the origin of the zygote,but it does not explain why every cell in the body retains the same genetic material as the zygote (which is due to the process of mitosis). Therefore,$R$ is not the correct explanation of $A$.

$A$: Every cell of the body contains the same genetic material as the zygote. $R$: The zygote is formed by the fusion of male and female gametes.
