why is genetic diversity so important?
24192
Genetic diversity serves as a way for populations to adapt to changing environments. With more variation, it is more likely that some individuals in a population will possess variations of alleles that are suited for the environment. Those individuals are more likely to survive to produce offspring bearing that allele.

Why protect biodiversity and save endangered species? Biodiversity is the variety of life (its ecosystems, populations, species and genes). Saving endangered species (plants and animals) from becoming extinct and protecting their wild places is crucial for our health and the future of our children.

Food security: why is biodiversity important? Agriculture and biodiversity have often been regarded as separate concerns. ... The nutritional and livelihood benefits of diverse production systems are one way of achieving food security. Such systems are also more resilient to climate induced events or other shocks.

Diversity-Stability Theory Biologically diverse communities are also more likely to contain species that confer resilience to that ecosystem because as a community accumulates species, there is a higher chance of any one of them having traits that enable them to adapt to a changing environment.

Ecosystems with higher biodiversity are more stable as they can easily adjust to changes. We are slowly realising that the future of our species on Earth depends on maintaining high biodiversity. Biodiversity is important for human wellbeing as it provides food, potential foods, industrial materials and new medicines.

Higher population genetic diversity in the abundant species is likely due to a combination of demographic factors, including larger local population sizes (and presumably effective population sizes), faster generation times and high rates of gene flow with other populations.

Biological diversity is quite important because its helps maintain the ecological balance in a system. Different animals and plants depend on one another to fulfill all of their needs. For example, we human beings depend on various animals and plants for our clothes, shelter and food.

Both inbreeding and drift reduce genetic diversity, which has been associated with an increased risk of population extinction, reduced population growth rate, reduced potential for response to environmental change, and decreased disease resistance, which impacts the ability of released individuals to survive and ...

Usually three levels of biodiversity are discussed—genetic, species, and ecosystem diversity. Genetic diversity is all the different genes contained in all individual plants, animals, fungi, and microorganisms. It occurs within a species as well as between species.

Biodiversity boosts ecosystem productivity where each species, no matter how small, has an important role to play. For example, A larger number of plant species means a greater variety of crops. Greater species diversity ensures natural sustainability for all forms of life.

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.

Modern biochemistry and knowledge of DNA have shown that mutations are always the result of a loss of information. Evolution or changes in species may result from natural selection working with biodiversity to select well adapted variations to environmental changes.

The ultimate source of all genetic variation is mutation. Mutation is important as the first step of evolution because it creates a new DNA sequence for a particular gene, creating a new allele. Recombination also can create a new DNA sequence (a new allele) for a specific gene through intragenic recombination.

Genetic variation is important to the process of evolution because of mutation, a change in the DNA that can be very effective. How does natural selection work on single gene traits? Natural selection on a single gene trait can lead to changes in allele frequencies and changes in phenotype frequencies.
