WebDec 23, 2024 · This information is used to compute the polygenic score of individuals not in the original sample. Individuals with a higher polygenic score (orange) are predicted to have a higher trait value (e.g. to be taller or to have a greater risk of disease), while those with a lower polygenic score are predicted to have a lower trait value (bottom graph). WebApr 18, 2024 · Intuitively this occurs because if population B has a larger value of an ascertained polygenic score than population A, then the ascertained trait-increasing alleles have by chance drifted up in population B (compared to A) and this imbalance will have induced directional selection for the rest of the trait-increasing alleles to decrease their … connected community at\u0026t customer service https://e-dostluk.com
