Assertion(A): Genes are responsible for the transfer of characteristics from the parents to the offspring.
Reason(R): Genes are present in the nucleus.
Both A and R are true but R is not the correct explanation of A
Nucleus has thread-like structures called chromosomes. Chromosomes carry genes which contain all the information needed by the cell to function and to reproduce. So, genes are responsible for inheritance i.e., transfer of characteristics from the parent to the offspring.
