Can Learned Behaviors Affect Genetic Inheritance?

[daflora]

hi guys.do u think some habit learned by someone can be passsed on to his or her children?

It certainly cannot be passed on genetically, but upbringing and environment play roles as well. So a child could pick up a habit from their parents simply because the child sees the parent performing the behavior and wants to mimic it.

thanks alot.but i have an impression that that has a lot to do with evolution.is that the case?

There are epigenetic effects - enviromental effects on genetic material - that are passed on to offspring. Some are obvious - exposure to radiation or mutagens - increases the likelihood of genetic defect diseases in children of parents who were exposed.

Another effect is the apparent DNA effects found in mothers and offspring living after a famine

So this does indicate that while envrionment can damage DNA, learning in and of itself does not damage DNA.
