Epigenetic And Gene-Environment?

[Double93]

What is the difference between Epigenetic Factors/Effects and The Gene-Environment Model (if any)?

[chanel5]

I would say they are the same thing. Epigenetics looks at how both biological and environmental factors affect the "switching on" of certain genes, and the gene-environment model looks at the interaction between existing genes and the environment. The only difference that I can see is that in the consideration of epigenetics, there is more of a proven causal effect, ie any given environmental event can be shown to cause changes in the activation of genetic effects, whereas with the gene-environment model, the relationship is purely correlational, so no causal effect can be assumed.

Isn't it nice when people acknowledge your efforts to help them?

Well, you'll know next time chanel5. I was treated the same way with the question below. Thanklessness seems to be a growing trait.

[chanel5]

True, bigbanana, it makes me wonder if the posters ever bother to come back and see if they have an answer to their question - or are they really rude enough to ignore the fact that someone has spoken to them.

Thank you very much for answering.

hi babies

the gene environment model would include HbS and its advantage in africa and its disadvantage in northern europe wouldnt it

you could the same for thalassaemia with and outside the med could nt you

neither of those count as epigenetic do they ?

what about the explosion of the variegate porphyria gene in Sarth Efrica in the eighteenth century ? ( population expanded so rapidly that darwin didnt have an effect ) or Tay Sachs in Poland ( around 1780 -1850 again rapid pop growth disallowed any Darwin effect
That is the environment NOT having an effect or interacting in an unexpected way

one must do these answers because people ask for help
not because we want to be thanked or get feedback ( or else you will wait a very long time)

//one must do these answers because people ask for help //

No Peter Pedant. A potential replier must first make a decision on whether he or she wants to answer. There is no MUST about it as none of us are compelled to answer.

Indeed, people do ask for help, but let's be honest and concede at least that an OP should have the courtesy to reply and acknowledge the reply in some way.

I don't desire or expect feedback regarding my replies as I am not out to see my replies classified as "Best Answer" or whatever. The sole exception for me is when I am mistaken over an answer I've provided as should be the case for all of us. Therefore, I shall not wait a very long time for something that I don't expect.

Peter, I think you need to research and expand your knowledge of the subject a little more before you suggest answers to this subject. There are major flaws in your reply.

oops sorry prof
not my specialist subject
