Why is genetic diversity important in populations?

Genetic diversity is important because it increases the chances of survival of a population under changing environmental conditions.

Key Points

Factor	Impact	Explanation
Survival	Higher chances	Different traits help some individuals survive
Disease Resistance	Not all affected	Variation prevents total loss
Adaptation	Better adjustment	Population can evolve with changes
Stability	Long term balance	Reduces risk of extinction

Stepwise Understanding

1. Population contains different genetic variations

2. Environment changes or new challenges appear

3. Some individuals have suitable traits

4. These individuals survive and reproduce

5. Population continues with adapted traits

Important Concept

Genetic diversity is the base for evolution and natural selection.

Real Insight

Monoculture farming (same type of crops) often faces higher risk because lack of diversity makes crops vulnerable, this is why diversity matters a lot.

So genetic diversity acts like a backup system for survival of species.
