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.
How does genetic diversity increase the chance of survival?
A genetically diverse population of individuals is more likely to survive than a population of individuals with similar genetic makeup. Variation allows some individuals within a population to adapt to the changing environment and natural selection allows the expression of those beneficial traits to persist.
How does genetic variation in a species affect the chance of survival?
Genetic variation describes naturally occurring genetic differences among individuals of the same species. This variation permits flexibility and survival of a population in the face of changing environmental circumstances.
How is genetic diversity beneficial to ecosystems?
Genetic diversity is important because it could ensure that certain groups of individuals, species, or populations will be able to adapt to certain environmental factors. Besides having to deal with environmental conditions, genetic diversity renders them the ability to resist emerging diseases and epidemics.
Why do you think biodiversity is important in the survival of the species?
Ecological life support— biodiversity provides functioning ecosystems that supply oxygen, clean air and water, pollination of plants, pest control, wastewater treatment and many ecosystem services. Recreation—many recreational pursuits rely on our unique biodiversity , such as birdwatching, hiking, camping and fishing.
How does genetic diversity affect biodiversity in an area?
The general impact of human activities on genetic diversity disrupts or diminishes the capacity for adaptation, speciation, and macroevolutionary change. This impact will ultimately diminish biodiversity at all levels.
How does variation among species affect their survival and maintaining stability of the ecosystem?
Increasing species diversity can influence ecosystem functions — such as productivity — by increasing the likelihood that species will use complementary resources and can also increase the likelihood that a particularly productive or efficient species is present in the community.
What increases the chances that a trait will be passed on to offspring?
Inherited traits are influenced by genes, which are passed on to offspring and future generations. … Natural selection means that traits that offer an advantage will most likely be passed on to offspring; individuals with those traits have a better chance of surviving. Evolution occurs by natural selection.
What does genetic diversity increase?
Because natural selection acts directly only on phenotypes, more genetic variation within a population usually enables more phenotypic variation. Some new alleles increase an organism’s ability to survive and reproduce, which then ensures the survival of the allele in the population.
Why is genetic diversity important to evolution?
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.
How does biodiversity increase stability in an ecosystem?
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 will increasing species diversity affect ecosystem?
Explanation: By increasing species diversity in an ecosystem, both the efficiency and the productivity of an ecosystem will increase. A greater species richness and diversity may cause ecosystems to function more efficiently and productively by making more resources available for other species.
