Why is genetic diversity important and how and why do we measure biodiversity?
Maintaining high genetic diversity allows species to adapt to future environmental changes and avoid inbreeding. Inbreeding, which happens when there are small, isolated populations, can reduce a species' ability to survive and reproduce. Biodiversity in a region by measuring species richness basically tallying the number of different species in an ecosystem it's something tangible that researchers can do and provides the evidence needed to protect different diverse habitats around the globe. Hence, due to genetic diversity, the varieties that are susceptible, die and the ones who can adapt to changes will survive. Genetic diversity is important for a healthy population by maintaining different varieties of genes that might be resistant to pests, diseases or other conditions.
Genetic diversity can be measured directly by looking at genes and chromosomes or indirectly by looking at physical features of the organisms and assuming they have a genetic basis. Using the genetic code is arguably the strongest method of measuring biodiversity as it is looking at the building blocks of life. All the biological data and variation that makes life on our planet work is encoded in DNA. This is known as genetic diversity. It strengthens the ability of species and populations to resist diseases, pests, changes in climate and other stresses. Hence, due to genetic diversity, the varieties that are susceptible, die and the ones who can adapt to changes will survive. Genetic diversity is important for a healthy population by maintaining different varieties of genes that might be resistant to pests, diseases or other conditions. Genetic Diversity refers to the range of different inherited traits within a species. In a species with high genetic diversity, there would be many individuals with a wide variety of different traits. Genetic diversity is critical for a population to adapt to changing environments. Biodiversity is increased by genetic change which increases a species' ability to adapt. Conversely, a population cannot evolve to adapt to environmental change without genetic diversity
