摘要

Environmental influences on epi-genetics are important for understanding the mechanisms and inheritance of biological variation. Some of the best models for mammalian epigenetics are the yellow alleles of agouti in mice. Alleles such as A~(vy) produce readily distinguished agouti, yellow, and mottled coat-color epigenetic phenotypes. Dietary and genetic variations during development affect the epigenetic phenotypes of offspring. Little is known regarding the gesta-tional timing of dietary treatments to affect epigenetics.
