Question

reproduction incorporates such a process of combining DNA from two
different individuals during reproduction.
But this creates a major difficulty. If each new generation is to be the
combination of the DNA copies from two pre-existing individuals, then
each new generation will end un having twice the amount of DNA that
the previous generation hau. This is likely to mess up the control of the
cellular apparatus by the DNA. How many ways can we think of for
solving this difficulty?​

Answer 1

Answer:

The amount of DNA remains constant because meiosis in the cells produces gametes. ... The gametes combine during the process of fertilisation and restore the original chromosomal number and thus maintain a constant amount of DNA through each generation.

During fertilization, haploid cells fuse to restore the chromosome number in the offspring. Hence, meiosis maintains constant number of chromosomes of particular species. A diploid zygote is formed after fertilisation. Hence the amount of DNA present in the chromosomes is restored and not doubled in each generation.
