Like father, like son. And also like daughter, according to new research.
The University of North Carolina School of Medicine released a study Monday indicating mammals are genetically more like their fathers than their mothers, according to a statement from UNC.
“Specifically, the research shows that although we inherit equal amounts of genetic mutations from our parents – the mutations that make us who we are instead of some other person – we actually ‘use’ more of the DNA that we inherit from our dads,” the statement reads.
Researchers tracked genetic mutations in nine kinds of mice bred from three genetically diverse inbred strains.They found that the offspring’s gene expressions were more heavily influenced by the male parent.
“If inherited from the mother, the (bad mutation) wouldn’t be expressed as much as it would be if it were inherited from the father,” according to UNC.
The statement suggests this kind of research could help those in the medical field better understand inherited diseases.
“The paper is very interesting and it has offered us new insights and a new perspective on the regulation of gene expression. But it leaves many open questions and that’s a good thing, not a bad thing,” Nicholas Katsanis, director of the Center for Human Disease Modeling at Duke University, told the USA TODAY Network.
When researchers study the genome mutations they don’t typically take into consideration a parent of origin, Katsanis said. This paper presents a case that they should.
“This adds another layer of biological complexity and serves as a very good reminder that just when we thought we understood the genome we don’t,” he said.
