WebPolygenic and X-linked are not mutually exclusive; a trait can be polygenic, X-linked, neither, or both.. Polygenic traits are those affected by many genes. According to Conner and Hartl, "Traits that are affected by many gene loci are often called polygenic traits." For example, childhood intelligence is affected by many genes throughout the genome. . Monogenic … WebApr 5, 2024 · We modeled polygenic IR as a quantitative trait by devising a Polygenic Resistance Score that can be measured as WHO cylinder bioassay survival. Previous models have applied a quantitative genetics framework to IR traits (Gardner et al., 1998 ; Haridas & Tenhumberg, 2024 ), but did not investigate the implications for resistance management …
