Genetically Speaking, You’re More Like Your Dad

You may have inherited your mother’s eyes, but, genetically speaking, you use more DNA passed down from your father. 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. The same is true for all mammals. But that doesn’t necessarily mean that mom and dad genes are equally active in creating who we are.

Researchers now report that thousands of mouse genes show parent-specific effects, and that on balance, the scales are tipped in favor of dads. Studying whether this imbalance exists in humans could give scientists insights into the causes of inherited conditions like diabetes and heart disease.
