Quotes About Heredity

The science of epigenetics has also made it clear that there are two mechanisms by which organisms pass on hereditary information. Those two mechanisms provide a way for scientists to study both the contribution of nature (genes) and the contribution of nurture (epigenetic mechanisms) in human behavior. If you only focus on the blueprints, as scientists have been doing for decades, the influence of the environment is impossible to fathom. (Dennis 2003; Chakravarti and Little 2003)

There are some things that are in you because of your DNA and some things that are a product of your environment and what you've been around.

It's amazing what the gene pool will do to perpetuate itself.

defective genes.

Mercado urged instead that people with the same defect not marry, because their children would be at greatest risk of developing the same hereditary disease. All people should seek out a spouse as different from themselves in as many individual characteristics as possible.

Each gene is a stretch of DNA, made up of thousands of bases.

When Adolf Hitler was imprisoned in 1924, he learned of the Kallikaks in a book he read about heredity. Soon after, Hitler wrote Mein Kampf, in which he mimicked the language of American eugenicists, declaring that sterilization of defective people "is the most humane act of mankind.

Something must happen to 'stir up their heredities,' as I am fond of saying—to excite in them the variability that normally lies dormant," Burbank later explained

If heredity is a kind of memory, methylation suffers radical amnesia in every generation.

When Morgan looked at the pedigrees of families like the Kallikaks, he did not see undeniable proof of the heredity of feeblemindedness. He saw instead many generations of poor people suffering enduring hardships. "It is obvious that these groups of individuals have lived under demoralizing social conditions that might swamp a family of average persons," Morgan wrote.

The "whole problem of heredity has undergone a complete revolution," Bateson declared. Mendel's discoveries could at last mature into a true science. Bateson christened it genetics.

Character isn't built, it's bred.

We mean by collective unconscious, a certain psychic disposition shaped by the forces of heredity; from it consciousness has developed. In the physical structure of the body we find traces of earlier stages of evolution, and we may expect the human psyche also to conform in its make-up to the law of phylogeny.

the only people that inherited anything by right of birth were the congenital idiots.

Heredity is nothing but stored environment.

Heredity is an omnibus in which all our ancestors ride, and every now and then one of them puts his head out and embarrasses us.

Two distinct elements are included under the term inheritance— the transmission, and the development of characters;

more commonly but not exclusively to the like sex. It is a fact of some importance to us, that peculiarities appearing in the males of our domestic breeds are often transmitted, either exclusively or in a much greater degree, to the males alone. A much more important rule, which I think may be trusted, is that, at whatever period of life a peculiarity

The laws governing inheritance are for the most part unknown.

But hereditary diseases and some other facts make me believe that the rule has a wider extension, and that, when there is no apparent reason why a peculiarity should appear at any particular age, yet it does tend to appear in the offspring at the same period at which it first appeared in the parent. I believe this rule to be of the highest importance in explaining the laws of embryology.

To Hell with all racialists,' she said aloud. 'And to Hell with eugenics, degenerate heredity, miscegenation and frauds who pile up skulls like a conqueror as well. May they choke on their bones.' A passing gentleman boggled at her and crossed to the other side of La Trobe Street. 'There is no place for them in the Kingdom of Heaven,' she added, rolling the phrase over her tongue and filing it for future reference.

Some might attribute my transformation to the laws of heredity. … But I think it was my reward for all those hours of work on the bridle path, the neighborhood sidewalks and the schoolhouse corridors.

It was foolish, the things a person would do because their parents had done the same.
