Squirrels exposed to pesticides present demethylation of genes associated with heart disease which is passed on to future generations even when they have not been exposed to pesticides. This scenario is a result of: Epigenetics and the environment because the exposure to pesticides influences the methylation of the gene The environment because the exposure to pesticides influences the expression of the gene Epigenetics because the expression of the gene depends on the exposure of the pesticide and methylation pattern Genetics because the methylation of the gene determines its expressionarrow_forwardHow would you explain gene expression?
