What is Genetic Variation?
Asked by Siddhartha Chandrashekhar · 2 years ago
What is genetic variation and why is it important in the context of evolution?
1 Answer
Genetic variation refers to the differences in DNA sequences among individuals within a population. This variation is crucial for the survival and evolution of species. Here's why:
1. Adaptation to Environment: Genetic variation allows populations to adapt to changing environments. Individuals with beneficial traits are more likely to survive and reproduce, passing those traits on to the next generation.
2. Evolution: It is the raw material for evolution. Natural selection acts on genetic variation, leading to the evolution of new species over time.
3. Health and Disease: Genetic variation can influence an individual's susceptibility to diseases. It can also affect how individuals respond to medications.
In summary, genetic variation is essential for the adaptability, survival, and evolution of species.
