Change in maternal environment induced by cross-fostering alters genetic and epigenetic effects on complex traits in mice.

Abstract excerpt

The interaction between maternally provided environment and offspring genotype is a major determinant of offspring development and fitness in many organisms. Recent research has demonstrated that not only genetic effects, but also epigenetic effects may be subject to modifications by the maternal environment. Genomic imprinting resulting in parent-of-origin-dependent gene expression is among the best studied of...
