Summary

Story summary

A Nature study shows that genetic traits can be influenced by the parent of origin, based on 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.
The study's innovative method inferred parental origin without direct genome access, enhancing sample size and reliability.
Results suggest paternal alleles promote growth, while maternal alleles limit it, affecting height and type 2 diabetes risk.
Future research will investigate molecular mechanisms and apply findings to psychiatric traits using diverse biobank data.
