Men who are stressed can pass on anxiety and depression to their children and grandchildren, scientists in Australia have found, in a study which indicates parental advice has been "disproportionately" focused on the health and diet of women. The study, based on mice which were fed stress hormones, examined the behaviour of the first and second generations of offspring. It found that the later generations – that had no contact with their fathers - showed signs of increased anxiety and depression and that such behaviour may be passed on via molecules called "microRNAs" which affected genetic outcomes. http://www.telegraph.co.uk/news/201...ety-and-depression-to-their-children-geneti/?
Up to 40 per cent of a child's intelligence is passed down from the parents, according to a new study. The finding from the largest ever genetic study of childhood intelligence adds yet more fuel to the debate over whether intelligence is a product of nature or nurture. Using genetic data and IQ scores of thousands of children from four countries, researchers from the University of Queensland found attempted to separate out the environmental effects. They found that between 20 and 40 per cent of the variation in childhood IQ is due to genetic factors, less than the 40 to 50 per cent suggested by previous research. They discovered an imbalance in the offspring which made their brain gene significantly more like their FATHER'S. http://googleweblight.com/?lite_url...664228&sig=AKOVD675XZ-l9vzmY4-NkRcodBDbkRggFQ Fathers who smoke pass on damaged DNA to their children –raising the risk of cancer, research shows. http://googleweblight.com/?lite_url...664228&sig=AKOVD66flAf2ub4PSi7wlV5H9DCfQb1GCA (2012) Dads: Your Bad Habits Can Pass Down to Your Children http://googleweblight.com/?lite_url...664228&sig=AKOVD679pAGQWnKrY4ctKN25nRTS0QEmUw And http://www.sciforums.com/threads/fathers-age-and-lifestyle-have-been-linked-to-birth-defects.156437/ of 2016.
