“Each generation is a filter, a sieve; good genes tend to fall through the sieve into the next generation; bad genes tend to end up in bodies that die young or without reproducing.”

“Geneticists will tell you that. Evolution is always happening. What they mean is that the genes of this generation are not precisely what they were the preceding generation. Nor will they be precisely the same in the next. And evolution is that change.”

“We can actually change the expression of genes—tumor suppressing genes, tumor activating genes—by what we eat, what we put into our bodies. So, even if you've been dealt a bad genetic deck, you can still reshuffle it with diet.”

“When you eat a healthy, whole foods, plant-based diet, it changes the expression of your genes. It turns on the good genes, turns off the bad genes. Your genes are a predisposition, but your genes are not your fate. And even if your mother and your father and aunts and uncles all died of diabetes, cancer, even heart disease, it doesn't mean that you need to.”

“Complex organisms cannot be construed as the sum of their genes, nor do genes alone build particular items of anatomy or behavior by themselves. Most genes influence several aspects of anatomy and behavior—as they operate through complex interactions with other genes and their products, and with environmental factors both within and outside the developing organism. We fall into a deep error, not just a harmful oversimplification, when we speak of genes “for” particular items of anatomy or behavior.”

“There is no gene “for” such unambiguous bits of morphology as your left kneecap or your fingernail. […] Hundreds of genes contribute to the building of most body parts and their action is channeled through a kaleidoscopic series of environmental influences: embryonic and postnatal, internal and external. Parts are not translated genes, and selection doesn't even work directly on parts.”

“… a gene might be able to assist replicas of itself that are sitting in other bodies. If so, this would appear as individual altruism but it would be brought about by gene selfishness.”

“Jacob and Monod found that in bacteria, genes are switched on and off by other genes. This led them to distinguish between effector genes and regulatory genes. Effector genes encode effector proteins… which mediate specific cellular functions. Regulatory genes encode proteins called regulatory proteins, which switch the effector genes on or off.”

“Jacob and Monod not only outlined a theory of gene regulation, they also discovered the first regulators of gene transcription. These regulators come in two forms—repressors, genes that encode the regulatory proteins that shut genes off, and as later work showed, activators, genes that encode the regulatory proteins that turn genes on.”
