🧬 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.
