The Avy аllele оf the Agоuti gene invоlves the insertion of а trаnsposable element upstream from the normal Agouti promoter. The transposable element carries a promoter that causes the over expression of the Agouti gene. Mice carrying this allele tend to have coat colors that are more yellow than mice that don’t have this transposable element. If pregnant female mice are fed a diet that contains chemicals that increase DNA methylation, how would you expect that this diet would affect the coat color of offspring carrying the Avy allele?
