A study of 440,000 people found that humans are increasingly choosing partners who share their genetics. The trend has intensified every decade for the past 60 years. Read Full Article #Genetics #Assortative mating #Populationgenetics
• 🧬 A study of 440,209 people in the UK and Estonia reveals that partners are becoming increasingly genetically similar over the past 60 years.
• 📈 This trend, known as assortative mating, has intensified decade by decade, with educational attainment showing a sharper increase than height.
• 👨👩👧👦 The researchers used a new method to estimate genetic similarity between partners by reconstructing parental genomes from their children's DNA, without needing direct partner genotypes.
• 🌍 The study, published on August 17, 2026, in Nature Human Behaviour, found consistent trends across both countries, suggesting this genetic sorting is not static.

A new study has found that genetic signatures of assortative mating, where people pair up with partners who share similar traits, have grown significantly stronger among more recently born generations in the United States, particularly regarding educational attainment and smoking habits.

The genetic signature of assortative mating appears to be growing stronger in the United States
Couples tend to resemble each other in schooling, drinking, and smoking. A study of hundreds of thousands of people suggests this matching leaves a measurable imprint in the genome, one that may have grown stronger in recent American generations.

🧬 A new study published in Behavior Genetics reveals genetic signatures of "assortative mating" (people choosing partners with similar traits) across generations in the UK and US.
📚 Genetic signatures for education and smoking similarity between partners have grown stronger in more recently born Americans compared to those born earlier in the 20th century.
🧬 The research, led by Gretchen R. B. Saunders of the University of Minnesota, analyzed genetic data from the UK Biobank and the All of Us Research Program, finding that educational attainment showed the highest spousal correlation (0.45) followed by weekly alcohol consumption (0.42).
👥 While partners resemble each other in observable traits and genetic scores, some of the gap is attributed to shared environments and mutual influence over time, not just direct genetic selection.
