How your behaviour can change your children’s DNA

New research into inheritance shows we can alter family traits for better or for worse. Jonathan Leake reports

For Beatrix Zwart being young means having fun. She works hard, and out of hours she plays hard — including plenty of nights on the town with her friends.

“I lead a similar lifestyle to a lot of young professionals in Britain and I don’t intend to have any children until I’m well into my thirties,” said Zwart, a 25-year-old Belgian who lives in London.

“I’ve never really thought my lifestyle now could have any effect on my future children or grandchildren.”

Until recently that would also have been the opinion of most scientists. Genes, it was thought, were highly resilient. Even if people did wreck their own DNA through bad diet, smoking and getting fat, that damage was unlikely to be passed to future generations.

Now, however, those assumptions are being re-examined. At the heart of this revolution is a simple but controversial idea: that DNA can be modified or imprinted with the experiences of your parents and grandparents. ation -->

Can you say, “inherit the sins of your father?”

A gets mad at D when D d’s too much. D calls it A’s fault. N is ambidextrous.

It makes sense that learned behavior might be passed to your offspring. All animals (and people) have instinctive behavior patterns that help them survive. If learned behavior could be passed to the offspring, this would be a huge advantage over waiting for blind chance to do the job.

For DNA modifications to be passed on to offspring there would have to be changes in the DNA of germline cells (i.e. ova, sperm). Whether or not environmental exposures (.e.g. stress, nicotine, alcohol, etc.) can alter the ‘epigenetics’ (e.g. DNA methylation patterns, histone acetylation etc.) of germline DNA remains unclear. What appears more clear is that the environment of the womb during embryonic development of a child is a crucial time during which what you eat, what drugs you take, what you drink, and whether or not you smoke can have a long-term effect on the child, even defining susceptibility to disease in adulthood.

I believe that the environment of the womb during embryonic development of a child is a crucial time and a lot depends on whether or not you are happy or stressed and angry.

Does this bring us back to the discussions of the early 20th century that birth defects are caused by traumatic encounters the mothers experience while pregnant? “She was scared by a lion at the zoo...”

Lamarck appears to have been on the right track, and even the Medieal alchemists were exceptionally astute to have anticipated “Super Atoms” (readily found on the internet) by over a thousand years!

Hmm, “bitter water” ~ a bad shipment of Evian perhaps?

I thought that was a default if one believes in inherited sin.
Or only when one is conceived via the parents’ sinning?
/sarc

I wrote a story of this same title, with the main character helping rebuild a post-apocalypse world as a terraformer (for Earth). The father who was thought dead, having been one of the architects of the disaster, supposedly defects to the daughter’s region. Nicer place to be, as it’s starting to live again. Makes main character’s life a very big problem, given her position and his, before his untimely death. Yet she has to live with the sins of her father, both in stigma and real world resonance.

Our family doctor told me to do my best to keep my wife away from stress and unnecessary anger while she was pregnant. Later, over lunch, we had a discussion about it and he gave me some of his experiences on the subject.

This is lifestyle police propaganda masquerading as bad science. What a crock.

Good advice.

My wife was pregnant with her daughter while her first marriage was falling apart.

The child (teen now) has been an emotional volcano her entire life, a deeply narcissistic personality.

My wife put had already put on a good deal of weight prior to becoming pregnant and put on more during the pregnancy.

The child was chunky as a youngster and is now obese.

I have no doubts about a mother’s mental condition during pregnancy affecting a child’s mental health. Certainly this is anecdotal but I see the evidence all around me that it is true.

Some would say that the divorce caused these personality traits but I was there and saw these traits in the child long before she was old enough to understand that her parents were separated.

It’s sad to hear about your child and your divorce when I am going towards the 35 year anniversary with my wife.
