उत्तर
- Mechanism: Sexually reproducing organisms maintain DNA stability through meiosis and fertilization.
- Meiosis: During meiosis, germ cells undergo division where the chromosome number is halved, ensuring each gamete carries only one set of DNA.
- Fertilization: This process restores the diploid state by combining two gametes, thus maintaining the species’ constant chromosome number.
- DNA Repair: Additionally, DNA repair mechanisms correct errors during replication, ensuring genetic stability across generations while allowing for minor variations needed for evolution.
