Question

How is the amount of dna maintained in each generation?

Answer 1

*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.

Answer 2

DNA in different generation

Explanation:

• During reproduction, the reproducing cells or germ cells have [*fr1] the quantity (amount) of chromosomes and deoxyribonucleic acid as compared to corporal or body cells or non-reproducing cells. because the offspring receives one deoxyribonucleic acid copy from every parent, this complicated mechanism helps to take care of the quantity of deoxyribonucleic acid constant in a personal.
• If the deoxyribonucleic acid had to urge doubled throughout reproduction, then every generation would have double the quantity of deoxyribonucleic acid content as compared to the previous generation. that's why the quantity of deoxyribonucleic acid doesn't get doubled throughout reproduction.
