New genetic research from the University of North Carolina is giving moms one more reason to collectively lose their bananas over dads getting credit for everything. Never mind that mom carried that baby until it shredded her lady bits and left the rest of her body in a permanent state of swell, studies on mice indicate that dads’ DNA has more influence on their offspring.
Perhaps you’re wondering if this just like a dad taking his baby grocery shopping and earning praise from strangers, while a mom doing the same is basically ignored? Not exactly.
Researchers found that although mammals inherit the same amount of DNA from each parent, they are more likely to use their dads’ genes, even when they look and act more like their mothers. Beyond giving society another reason to give dads a collective pat on the back, the finding provides scientists with new insight on how genetic diseases are expressed in individuals.
“We now know that mammals express more genetic variance from the father,” said senior study author Dr. Fernando Pardo-Manuel de Villena. “So imagine that a certain kind of mutation is bad. If inherited from the mother, the gene wouldn’t be expressed as much as it would be if it were inherited from the father. So, the same bad mutation would have different consequences in disease if it were inherited from the mother or from the father.”
That last bit should come as a relief to moms, who can rest assured they really are doing their best to give their kids everything – just not their diseases.
On a more serious note, we love dads, especially the good ones, and understand that any science that helps us understand — and hopefully avoid — disease is good science. Now please, go hug a dad, but don’t forget that moms are pretty amazing, too.
