Summary

Story summary

A study in Nature shows that genetic traits can vary based on the parent of origin, using data from over 100,000 UK Biobank individuals.
Researchers found over 30 "parent-of-origin effects," especially in growth and metabolism traits, supporting parental conflict theory.
Innovative methods improved parental origin assignment of genetic variants, validating results across multiple cohorts.
Findings reveal opposing effects of the same genetic variant on traits like height and type 2 diabetes risk.
Future research will investigate molecular mechanisms and psychiatric traits, deepening understanding of parent-specific genetic influences.
