Wow. A survey that confirms liberals have different genetic make up than normal folk.
Actually, all humor aside, "While the sequence of DNA may not be affected by your environment, the way genes work—called gene expression—can."
DNA is like a book about how to build a person, and genes are like sentences. So can these sentences be changed? According to Cedar, these letters are written in ink. You can’t add or modify them. But “it turns out that this text can be annotated,” he said. The secret to this change is “methyl groups.” These chemicals “tell the cells what should be read and what should not be read,” Cedar told us. They’re sort of like a black marker that you can use to cross out sentences, a process unsurprisingly called “methylation.” DNA may be unchangeable, but methyl groups are different. “Methylation can be changed.” This means your body-making instructions can change too.
Mounting evidence suggests that environmental factors such as smoking, diet and stress, can leave their mark on the genes of your children and grandchildren.
