TIME Science Research Humans Are Genetically More Similar to Their Fathers, Study Finds Sorry mom

Every parent wants their child to be just like them, but new research shows that dads may have an advantage at least from a genetic standpoint.

According to a study by the University of North Carolinas School of Medicine and published in the journal Nature Genetics, mammals use more DNA from the father than the mother when undergoing mutations the genetic process that makes us who we are.

The researchers, led by genetics professor and senior author Fernando Pardo-Manuel de Villena, tested the genetic mutations of specially crossbred mice to see which mutations altered gene expression. Of the 80% that did, several hundred genes showed a genome-wide expression imbalance in favor of the dad, first author James Crowley told Science Daily. This imbalance resulted in offspring whose brain-gene expression was significantly more like their fathers.

The authors believe a similar bias would exist for human subjects. Pardo-Manuel de Villena called the results an exceptional new research finding that opens the door to an entirely new area of exploration in human genetics.
