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 Carolina’s 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 father’s.”

The authors believe a similar bias would exist for human subjects. Pardo-Manuel de…
