WebAlthough polygenic risk scores gained increased attention within humans, the basic idea was first introduced for selective plant and animal breeding. Similar to the modern … WebPolygenic scores must be estimated from a finite training sample, and their effectiveness for association testing and risk prediction depends on the precision of this estimation as well as the proportion of variation explained by the polygenic score. The role of the sample size has not been thoroughly considered in this context.
