(a) Variation in DNA is beneficial for the survival of species over time. Explain.
- Variation in organisms is the degree by which a progeny differs from their parents .
- It allows for diversity in organisms.
- This diversity is important as it allows for the development of new traits , including faster adaptation to changes in the surrounding.
- In case of drastic alteration of niches, a population without variation is most likely to be wiped out .
- But a population with variation could have some surviving members to ensure continuity of species.
