WebGenetic variation is a major source of phenotypic variation, the engine of evolution, and an important cause of human pathology. Genetic variation exists along a continuum, from genomic changes at the level of entire chromosomes to single nucleotide changes. Phenotypic effects similarly range from negligible to life-threatening genetic disease. Weblines, while completely eliminating genetic variation; hence, the term epiRILs—epigenetic recombinant inbred lines. Perhaps the first question that springs to mind is why any epigenetic variation would persist in the epiRILs. One might expect that epigenetic variation generated in the met1 or ddm1 mutant parent would be reset after
