An experiment was conducted with two groups of genetically identical female agouti mice (Avy/a) that were mated with normal (a/a) male mice . Both female groups ate lab chow with bisphenol A (BPA) (50mg/Kg). (BPA, used in the manufacture of polycarbonate plastics, has estrogenic effects that include decreased CpG methylation.) The lab chow of one group was supplemented with methyl donors (e.g., folate, choline, and vitamin B12). The effects of BPA were abolished in the Avya offspring of the mice fed with the methyl donor–supplemented chow (i.e., the coat color distribution observed was shifted toward brown). Explain.
