Mongooses inherit behavior from role models rather than parents

Young mongooses learn lifelong habits from role models rather than inheriting them from genetic parents, new research shows.Banded mongooses live in social groups where pups are consistently cared for one-to-one by a single ...

Does physical activity influence the health of future offspring?

Physical and mental exercise can affect the learning ability of future offspring, at least in mice. This particular form of inheritance is mediated by certain RNA molecules that influence gene activity. These molecules accumulate ...

Discovering a new mechanism of epigenetic inheritance

Giacomo Cavalli's team at the Institute of Human Genetics (University of Montpellier / CNRS), in collaboration with the French National Institute for Agricultural Research (INRA), has demonstrated the existence of transgenerational ...

New view of germ cells

It has been accepted wisdom for decades that most animals create germ cells ― those cells that produce the eggs and sperm organisms need to pass on their genes ― in the same way.

Biological mechanism passes on long-term epigenetic 'memories'

According to epigenetics—the study of inheritable changes in gene expression not directly coded in our DNA—our life experiences may be passed on to our children and our children's children. Studies on survivors of traumatic ...

Equal inheritance growing less common, study finds

Anyone counting on an inheritance should be aware that in recent years, parents have become increasingly likely to divide their estates unequally, suggests a new study co-authored by an economist at Washington University ...

New insight into leaf shape diversity

Many of us probably remember the punnett squares by which we were introduced to the idea of genetic inheritance in school: a dominant allele in each of my brown-eyed parents hides a recessive allele that explains my blue ...
