Question

Effect of environmental factors on genetics

Answer 1

when two different genotypes respond to environmental variation in different ways. A norm of reactionis a graph that shows the relationship between genes and environmental factorswhen phenotypic differences are continuous.[1] They can help illustrate GxE interactions. When the norm of reaction is not parallel,there is a gene by environment interaction. This indicates that each genotype responds to environmental variation in a different way.

Answer 2

Explanation:

Apart from true single gene disorders, environmental factors, or environmental triggers, may determine the development of disease in individuals genetically predisposed to a particular condition. Environmental triggers may include stress, physical and mental abuse, diet, exposure to toxins, pathogens, and radiation.
