What Do Studies of Insect Polyphenisms Tell Us about
... Understanding the role of epigenetic mechanisms in insect polyphenisms is perhaps the best way to begin to untangle the basic biology underpinning the impact of diet on phenotype. Such studies are beginning to provide important insights into nutritional epigenetics. 2. DNA Methylation and Nutritiona ...
