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
In the nucleus, thread-like structures called chromosomes are present.These carry genes which contain all the information needed by the cell to function and to reproduce. IGenes are also responsible for all the characteristics of an individual. Thus, genes are responsible for inheritance i.e., transfer of characteristics from the parent to the offspring.
