WebSep 27, 2024 · Consequently, the educational attainment polygenic score is considered to be one of the most powerful polygenic scores in psychology, and it has been widely used in research demonstrating associations between the genetic influences on educational attainment and other phenotypes, such as longevity of parents (Marioni et al., 2016), … WebFeb 28, 2024 · This inheritance pattern is called polygenic inheritance ( poly – = many). For instance, a recent study found over 400 genes linked to variation in height [1]. When there are large numbers of genes involved, it becomes hard to distinguish the effect of each individual gene, and even harder to see that gene variants (alleles) are inherited ...
