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 situation. A characteristic that is determined by genetic factors is a feature which is coded for in a person's genetics, inherited from their parents, as opposed to environmental factors which are caused by the conditions they are exposed to after birth.

Environmental factors such as diet, temperature, oxygen levels, humidity, light cycles, and the presence of mutagens can affect the genes and result in the physical expression i.e. the phenotype. Genetic factors mean the DNA and allied properties. There are different from the environment. Tut these 2 influencing factors together decide the fate of species/ individual.

Environmental factors often influence traits independently of genes. But not always 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. 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. Science tells us that the interactions between genes and environment shape human development. Despite the misconception that genes are “set in stone,” research shows that early experiences can determine how genes are turned on and off and even whether some are expressed at all. The genetic factor is also called internal factor because the basis of plant expression is located within the cell. The environmental factor is considered external, and refers to all factors, biotic and abiotic, other than the genetic factor. Both plant growth factors interact in various ways. Genetic factors as well as local conditions affect the growth of an adult plant. The growth of an animal is controlled by genetic factors, food intake, and interactions with other organisms, and each species has a typical adult size range.
