Ecogenetics is a branch of genetics that studies genetic traits related to the response to environmental substances. Or, a contraction of ecological genetics, the study of the relationship between a natural population and its genetic structure.  Ecogenetics principally deals with effects...What is epigenetics in medical terms?
Medical Definition of epigenetics : the study of heritable changes in gene function that do not involve changes in DNA sequence At its most basic, epigenetics is the study of changes in gene activity that do not involve alterations to the genetic code but still get passed down to at least one successive generation.What is an example of ecogenetics in respiratory diseases?
Ecogenetics. Respiratory diseases There are three genetically-based respiratory diseases that can directly correspond with ecological functions and induce disease. These include lung cancer and the upper and lower respiratory tract associated with a serum Ig A deficiency.How does the environment affect epigenetic changes?
Some epigenetic changes can be added or removed in response to changes in behavior or environment. Smoking can result in epigenetic changes. For example, at certain parts of the AHRR gene, smokers tend to have less DNA methylation than non-smokers. The difference is greater for heavy smokers and long-term smokers.
