SNPwatch: Researchers Identify Genetic Variation That Contributes to Skin Color Differences in East Asians

From rich brown to almost translucent white, human skin colors span a remarkable spectrum. The evolutionary story of how we came to be such a varied species skin color-wise began around 40,000 years ago when the human groups that had left Africa and spread out along the southern coast of Asia began to ...

SNPwatch: New Psoriasis SNPs Found for both Europeans and Asians

SNPwatch gives you the latest news about research linking various traits and conditions to individual genetic variations. These studies are exciting because they offer a glimpse into how genetics may affect our bodies and health; but in most cases, more work is needed before this research can provide ...
