n.— «As Robert Brandon famously stated, genes are invisible to selection. Yet, population genetics assumes that the genes are visible to selection. How? Via phenotypes. But that is an oversimplified notion that a mutation in one gene predictably leads always to the same change in the phenotype. This one-gene one-trait view is sometimes called “bean-bag genetics.”» —“Books: “Biased Embryos and Evolution” by Wallace Arthur” by Coturnix Blog Around the Clock July 8, 2007.
