Quotes About Heredity

Gregor Mendel's years of research with green and yellow peas showed that such a thing must exist. Colors and other traits vary depending on many factors, such as temperature and soil content, but something is preserved whole; it does not blend or diffuse; it must be quantized.

Heredity is what sets the parents of a teenager wondering about each other.

in 1910 a Danish botanist, Wilhelm Johannsen, self-consciously invented the word gene. He was at pains to correct the common mythology and thought a word might help. The myth was this: that "personal qualities" are transmitted from parent to progeny. This is "the most naïve and oldest conception of heredity," Johanssen said in a speech to the American Society of Naturalists. It was understandable.

Mixing up your genotype with someone else's, possibly breaking up some bad genetic combinations that had been riding around in you, perhaps discovering new good combinations, and giving your offspring a chance at being a better fit in a landscape that has not yet occurred—these are the benefits of sexual reproduction.

Asking if a particular trait is due to nature or nurture implies a false dichotomy between nature, genes, and evolution on the one side and between nurture and environment on the other. In fact, all of it is evolutionary.

Custom gives the same stability to the group that heredity and instinct give to the species, and habit to the individual.

Liberty and equality are enemies: the more freedom men enjoy, the freer they are to reap the results of their natural or environmental superiorities; hence inequality multiplies under governments favoring freedom of enterprise and support of property rights.

Most revolutions find that they can check inequality only by limiting liberty, as in authoritarian lands.

Heredity and Environment are the master-influences of the organic world. These have made all of us what we are. These forces are still ceaselessly playing upon all our lives. And he who truly understands these influences; he who has decided how much to allow to each; he who can regulate new forces as they arise, or adjust them to the old, so directing them as at one moment to make them cooperate, at another to counteract one another, understands the rationale of personal development.
