Genetic diversity is often considered the most precise measure of biodiversity. It assesses the genetic variation within species, populations, or ecosystems, offering insights into adaptability and resilience. Unlike species diversity or ecosystem diversity, genetic diversity captures the subtle yet significant differences that play a crucial role in the survival and evolution of species.

FAQs & Answers

  1. What are the different types of biodiversity? The main types of biodiversity are genetic diversity, species diversity, and ecosystem diversity, each playing a vital role in ecological health.
  2. Why is genetic diversity important for species survival? Genetic diversity enhances adaptability and resilience, helping species cope with environmental changes and threats.
  3. How can we measure biodiversity? Biodiversity can be measured through various methods including assessing genetic variation, counting species, and evaluating ecosystem health.
  4. What are the threats to biodiversity? Threats include habitat loss, climate change, pollution, and invasive species, all of which can diminish genetic diversity and ecosystem stability.
