Quotes About Genetics

In addition to single-gene genetic disorders, there are just five causes of all disease: poor diet, chronic stress, microbes, toxins, and allergens, all of which wash over our DNA causing changes in our gene expression, and turning off or on different genes and messages that affect our metabolism.

Your zip code is a bigger determinant of your health outcomes than your genetic code.

A secretor is somebody whose blood type appears in his or her body fluids as well as in the blood itself—handy if all you've got is a sweaty shirt or, as in this case, semen. A nonsecretor's blood type can only be ascertained through the blood.

there's something fundamentally wrong with the wiring of our brains, which makes us incapable of consistent logical thinking.

Life is a DNA software system.

The X chromosome does most of the heavy developmental lifting, while the little Y has been shedding its associated genes at a rate of about five every one million years, committing suicide in slow motion. It's now down to less than 100 genes. By comparison, the X chromosome carries about 1,500 genes, all necessary participants in embryonic construction projects. These are not showing any signs of decay.

MZ twins are as closely related to their nieces and nephews as they are to their own children.

The effect of hallucinogenic mushrooms on the user's experience and behavior depends in part on his or her personality and genetic predisposition, which can vary to a great extent from person to person.

To be genetically correct, man needs a modern version of a Neo-Paleolithic diet, a diet that's based on his current genetic makeup. That's exactly what a Zone-favorable diet is: a diet that is synergistic with mankind's genetic structure, which has changed very little in the last 100,000 years.

Where does a child of mine get all that hair, I wonder? Arthur's not exceptionally hirsute, and the men on my side of the family are as bald as potatoes.
