Positive Selection in East Asians for an EDAR Allele that Enhances NF-κB Activation: Genome-wide scans for positive selection in humans provide a promising approach to establish links between genetic variants and adaptive phenotypes. From this approach, lists of hundreds of candidate genomic regions for positive selection have been assembled. These candidate regions are expected to … Continue reading Positive selection on EDAR, why East Asians & Native Americans have thick hair
