Environmental factors such as soil nutrients, temperature, water availability and light intensity influence the genetic and chemical diversity of plant populations. These environmental conditions can exert strong selection pressures, they could even determine the evolutionary course of plant populations Environmental factors often influence traits independently of genes. Sometimes the environment changes a gene either its DNA sequence or its activity level. Either of these effects can change the proteins that are made from a gene, which in turn affects traits. Variation among individuals of the same species can be explained by both genetic and environmental factors.

The genetic variability created by the mutation will be tested by natural selection, which determines what characteristics are inherited in a population over time. Environmental factors such as soil nutrients, temperature, water availability and light intensity influence the genetic and chemical diversity of plant populations. These environmental conditions can exert strong selection pressures; they could even determine the evolutionary course of plant populations. A number of environmental factors can impact natural selection. Climate, habitat type, available food, and a habitat's predators can all impact which traits will be selected. Sometimes the environment changes a gene either its DNA sequence or its activity level. Either of these effects can change the proteins that are made from a gene, which in turn affects traits. Some harmful environmental factors can change a gene's nucleotide sequence. For example, UV radiation can break DNA strands. Beneficial mutations are passed on and harmful mutations are eliminated as organisms adapt to changing environmental conditions and evolve. Genetic diversity is influenced by four events controlling evolution: mutation, genetic drift, gene flow, and natural selection. The environment creates selective pressure that is one of the driving factors in natural selection. Changes in the environment allow for some organisms to survive better than others within a species. Environmental factors, as related to genetics, refer to exposures to substances where we live or work behaviors that can increase an individual's risk of disease or stressful situations. Genetic variations that alter gene activity or protein function can introduce different traits in an organism. If a trait is advantageous and helps the individual survive and reproduce, the genetic variation is more likely to be passed to the next generation. As conditions change, natural selection favors one allele or genetic variant over another. Genes that can facilitate a range of different forms under different environments can also help an organism adapt to changing conditions. If the environment changes rapidly, some species may not be able to adapt fast enough through natural selection. Through studying the fossil record, we know that many of the organisms that once lived on Earth are now extinct. It strengthens the ability of species and populations to resist diseases, pests, changes in climate and other stresses. Gene variations underpin their capacity to evolve and their flexibility to adapt. In addition to demographic processes, ecological and environmental factors can also play a role in shaping genetic diversity patterns. Organisms are born with specific traits inherited from their parents, but the environment can influence them. In cases where food is limited, a typically massive animal may be skinny, or shade over a plant may cause it to be stunted in growth. Instead, most diseases are complex and stem from an interaction between your genes and your environment. Factors in your environment can range from chemicals in air or water pollution, mold, pesticides, diet choices, or grooming products.

Some variation is passed on from parents to offspring, via genes during reproduction. This is inherited variation. Some variation is the result of differences in the surroundings, or what an individual does. Inherited traits are the traits you get from your parents through the genes they pass down to you, their offspring. Environmental traits are influenced by your environment. Heritability is the ratio of genetic variance (VG) to phenotypic variance (VP) and ranges from 0 to 1. High heritability values of 0.5 mean that on average half of the differences among phenotypes of animals are genetic. Low values of approximately 0.1 mean that most of the differences are not genetic.Positive experiences, such as exposure to rich learning opportunities, and negative influences, such as malnutrition or environmental toxins, can change the chemistry that encodes genes in brain cells a change that can be temporary or permanent. This process is called epigenetic modification.
