Complex Traits and Polygenic Scores

Variable prediction accuracy of polygenic scores within an ancestry group (bioRxiv)

F1.large

Signals of adaptation of height, based on polygenic scores, are mostly an artifact of population structure confounding (eLife)

Also see this eLife editorial and article on Quanta Magazine covering the paper.

Selective constraint on gene expression (Genetics)

Statistical Learning about Molecular Processes

What determines the distribution of allele frequencies in humans in large samples?  We found surprising effects of two evolutionary forces, mutation rate variation and fitness epistasis. (PLoS Genetics)badgef1000
