How does the environment interact with genotypes?

Sometimes, sensitivity to environmental risk factors for a disease are inherited rather than the disease itself being inherited. Individuals with different genotypes are affected differently by exposure to the same environmental factors, and thus gene–environment interactions can result in different disease phenotypes.

What is an example of a gene environment interaction?

For example, people with blue eyes have the gene variant, or genotype, that produces the observable phenotype of blue eyes. In many genes, different variants (genotypes), alter the expressed outcomes (phenotype) even when exposed to the same environmental exposure.

What are types of genotype environment correlation?

We define three types of genotype–environment correlation (passive, evocative, and active), describe the evidence from quantitative and molecular genetic studies for their existence, and discuss the implications of genotype–environment correlations for the prevention and treatment of psychiatric disorder.

Does environment affect genotype?

Genotype generally remains constant from one environment to another, although occasional spontaneous mutations may occur which cause it to change. These phenotypic variations are attributable to the effect of the environment on the expression and function of genes influencing the trait.

What is active genotype environment?

Active genotype-environment correlation occurs when individuals seek out environments that support their genetic tendencies. This is also referred to as niche picking. For example, children who are musically inclined seek out music instruction and opportunities that facilitate their natural musical ability.

What are some examples of environmental factors?

Environmental factors include temperature, food, pollutants, population density, sound, light, and parasites. The diversity of environmental stresses that have been shown to cause an increase in asymmetry is probably not exclusive; many other kinds of stress might provide similar effects.

What are the natural factors affecting environment?

An environmental factor, ecological factor or eco factor is any factor, abiotic or biotic, that influences living organisms. Abiotic factors include ambient temperature, amount of sunlight, and pH of the water soil in which an organism lives.
