Genetics of Blood (IMAGE) University of Montreal Caption Researchers discovered 5000 genetic associations and used the genetic diversity of their samples to refine association signals and explored the genetic architecture of blood-cell traits across populations. This image illustrates how the authors used genetic data from 746,667 participants from five global populations (African-ancestry, East Asian, European-ancestry, Latino/Hispanic, South Asian) to investigate the number, size or feature of red blood cells (red), white blood cells (purple), and platelets (beige).
