Question

This double set remains inside all the cells of the body till meiosis cell division takes place in reproductive mother cells.explain

Answer 1

Here double set means two sets of chromosomes. every cell of the body (except gametes) are diploid means have two sets of chromosomes (46 chromosomes) where as gametes are haploid having one set of chromosomes (23 chromosomes).

Statement implies that every cell of the body remain diploid until they undergo meiosis to produce four cells each with one set of chromosome (haploid). in our body meiosis occurs only in the reproductive mother cells that later on produce gametes.
