Reply to comment by HurpDurp54 in Low doses of alcohol play a role in epigenetics and changes within the brain by HurpDurp54

'role in epigenetics' means that this effect is observed even in mature people? or is it still limited to fetuses?

Epigenetics is when the environment, or in this case, behavior and consumption of alcohol can change DNA expression. In itself, it does not affect gametes, it is simply a change in expression (it becomes available to transcription proteins). Part of the discussion describes how some people may be more suceptible to these DNA expression changes, and may explain hereditary addiction. Possibly it is a mechanism to keep the brain in homeostasis.

That typo is so epic it's almost not worth correcting. Literally how I would mis-pronounce the word.

Phenotype = genotype (your genes) + environment (your life, diet, behavior, habits, etc)

Epigenetics is about the expression of your genes, i.e. chages that can occur without having a DNA change.
