Assortative mating on blood type: Evidence from one million Chinese pregnancies.

Proceedings of the National Academy of Sciences of the United States of America - 20 Dec 2022

Abstract excerpt

Blood type is one of the most fundamental phenotypes in biological, medical, and psychological studies. Using a unique dataset of one million Chinese pregnancies, we find strong evidence from a group of statistical tests for assortative mating on blood type. After controlling for anthropometric and socioeconomic confounders, assortative mating remains robust.
