What is the effect of DNA copying, which is not perfectly accurate, on the reproduction process ? How does the amount of DNA remain constant though each new generation is a combination of DNA copies of two individuals ?
(i) DNA copying leads to more variations in the offspring.
(it) Sexually reproducing organisms have special lineage of cells which have only half the amount of DNA/ half the number of chromosomes as the parent cell.
(iii) When such germ cells fused, a new individual is formed with the same amount of DNA as that of parent.
