Vedclass · Answer

(A) $(i)$ $DNA$ copying that is not perfectly accurate leads to variations in the offspring,which is the basis of evolution.$(ii)$ In sexually reproducing organisms,specialized germ cells (gametes) are produced through meiosis,which contain only half the amount of $DNA$ or half the number of chromosomes compared to the parent cell.$(iii)$ When these haploid germ cells fuse during fertilization,the resulting zygote restores the original amount of $DNA$ characteristic of the species,ensuring the amount remains constant across generations.

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?
