"The findings provide evidence of "transgenerational epigenetic inheritance" -
One of the researchers Dr Brian Dias told the BBC: "This might be one mechanism that descendants show imprints of their ancestor.
There is absolutely no doubt that what happens to the sperm and egg will affect subsequent generations."
Experiments showed that a traumatic event could affect the DNA in sperm and alter the brains and behavior of subsequent generations.
A Nature Neuroscience study shows mice trained to avoid a smell passed their aversion on to their "grandchildren".
"The experiences of a parent, even before conceiving, markedly influence both structure and function in the nervous system of subsequent generations," the report concluded."

Experts said the results were important for phobia and anxiety research.
The animals were trained to fear a smell similar to cherry blossom..jpg)
The team at the Emory University School of Medicine, in the US, then looked at what was happening inside the sperm.
They showed a section of DNA responsible for sensitivity to the cherry blossom scent was made more active in the mice's sperm.
Both the mice's offspring, and their offspring, were "extremely sensitive" to cherry blossom and would avoid the scent, despite never having experienced it in their lives.
Changes in brain structure were also found.
