How does genetic variation determine biodiversity?

How does genetic variation determine biodiversity?

Genetic variation is an important force in evolution as it allows natural selection to increase or decrease frequency of alleles already in the population. Genetic variation is advantageous to a population because it enables some individuals to adapt to the environment while maintaining the survival of the population.

Why is genetic diversity important to biodiversity?

Genetic diversity is important because it helps maintain the health of a population, by including alleles that may be valuable in resisting diseases, pests and other stresses. If the environment changes, a population that has a higher variability of alleles will be better able to evolve to adapt to the new environment.

How do genetics and heredity contribute to biodiversity on Earth?

Greater biodiversity in ecosystems, species, and individuals leads to greater stability. For example, species with high genetic diversity and many populations that are adapted to a wide variety of conditions are more likely to be able to weather disturbances, disease, and climate change.

How does gene mutation affect biodiversity?

Mutations increase the amount of diversity within a population/species. Mutations are the primary source of genetic diversity. By introducing new alleles into the population, the population becomes more heterogeneous. This is the same principle with mutations and populations different species.

Where is maximum biodiversity found?

Most of the terrestrial diversity is found in tropical forests and in general, the land has more species than the ocean; some 8.7 million species may exist on Earth, of which some 2.1 million live in the ocean.

Which region has maximum biodiversity in India?

It hosts 4 biodiversity hotspots: the Himalayas, the Western Ghats, the Indo-Burma region and the Sundaland (Includes group of Islands). These hotspots have numerous endemic species….Species estimates.

Taxonomic Group Total (Protista)
World species 31250
Indian species 2577
% in India 8.24

Which has maximum genetic diversity in India?

Among the following crops, Mango also known as Mangifera indica is the plant with the highest genetic diversity in India.

Which species has maximum diversity?

Hint: Biodiversity is the variety of life on earth. It includes all different plants, animals, and microorganisms. The maximum diversity is seen in members of the group of eukaryotic organisms that includes microorganisms such as yeasts and moulds. Fungi reflect the largest number of species in global biodiversity.

What are the factors that affect biodiversity?

Major threats to biodiversity are:

  • Habitat destruction/Deforestation.
  • Introduced and invasive species.
  • Genetic pollution.
  • Over exploitation.
  • Hybridization.
  • Climate change.
  • Diseases.
  • Human over-population.

How do humans contribute to the loss of biodiversity?

The main cause of the loss of biodiversity can be attributed to the influence of human beings on the world’s ecosystem, In fact human beings have deeply altered the environment, and have modified the territory, exploiting the species directly, for example by fishing and hunting, changing the biogeochemical cycles and …

What are major threats to biodiversity?

Five main threats to biodiversity are commonly recognized in the programmes of work of the Convention: invasive alien species, climate change, nutrient loading and pollution, habitat change, and overexploitation.
