PATHOLOGY

Detailed explanation-1: -Gene–environment interactions are the situation where the impact of an environmental exposure on disease risk is different for people with different genotypes, or conversely, situations where the impact of a genotype on disease risk is different in people with different environmental exposures.

Detailed explanation-2: -Environmental factors influence traits in plants and animals. These traits include things like weight, height, size, and color. If a child does not get proper nutrition, their height may be stunted as an adult.

Detailed explanation-3: -The interaction between the genetic factors and environmental stimulus is what results in the disease phenotype.

Detailed explanation-4: -Environmental factors such as diet, temperature, oxygen levels, humidity, light cycles, and the presence of mutagens can all impact which of an animal’s genes are expressed, which ultimately affects the animal’s phenotype.
