That’s the conclusion of a new study on mice that researchers say likely applies to all mammals.We humans get one copy of each gene from mom and one from dad (ignoring those pesky sex chromosomes) that hasn’t changed. But that doesn’t necessarily mean that mom and dad genes are equally active in creating who we are.These mice were specifically bred to mimic the genetic diversity found in human populations.Scientists interbred three strains of these mice to create nine different types of offspring.There was no way I could keep that dating fire burning as practicality invaded our lives. Something I haven’t wanted to admit for a long time, but is undeniable. And even worse, it seemed that the harder I tried to be sentimental and lovey-dovey, the less it was reciprocated. Or, once we had a daughter, when I shared the responsibility of watching over her. Because as our marriage progressed, I found myself offering to help out around the house more and more. It took me longer than I care to admit to understand what was happening. Through giving, through doing things for my wife, the emotion that I had been so desperately seeking naturally came about. An emotion that, once had, somehow magically stays within a marriage forever. And I’m saddened to think about how much those messages bounced around in my head for so long.Humans, mice and many other animals shared a common ancestor some 80 million years ago; therefore, our set of genes are highly alike.
Experts said if fathers are involved, mothers are less stressed – which in turn improves children’s wellbeing and diet.The study looks at gene expression that is, genes’ level of activity in producing RNA, which is the molecule that then goes on to create proteins and basically make the body function.In this study, scientists worked with a population of mice called the Collaborative Cross, which is the most genetically diverse population of mice in the world.Fathers also have a unique impact as they are more likely to engage in active play with their child, meaning they do more physical exercise and get outside more.The scientists, from Johns Hopkins University School of Public Health in Baltimore and Harvard School of Public Health, tracked 3,900 children in the US from the age of two until they turned four.
