Phenotype Quotes

There's this very interesting and complicated connection between our environment and our genes and the traits that come out of the environment plus genes. And there's huge potential. I mean we see amazing abilities. Marie Curie, Albert Einstein. All sorts of arts, and literature and so forth. These are not typical traits of everybody on earth.

My genetics are good, but they aren't crazy He-Man style.

Heredity is nothing but stored environment.

Some of the exponents of this theory of heredity have attempted to elude the difficulty of placing a whole world of wonders within a body so small and so devoid of physical structure as the germ.

These signal diversities which constitute differences of race in animals... can only be explained by two principles... namely, the occasional production of an offspring with different characters from those of the parents, as a native or congenital variety; and the propagation of such varieties by generation.

We know virtually all of the genes known to mammals. We do not know all of the combinations.

My experiments with single traits all lead to the same result: that from the seeds of hybrids, plants are obtained half of which in turn carry the hybrid trait (Aa), the other half, however, receive the parental traits A and a in equal amounts. Thus, on the average, among four plants two have the hybrid trait Aa, one the parental trait A, and the other the parental trait a. Therefore, 2Aa+ A +a or A + 2Aa + a is the empirical simple series for two differing traits.

Each race (or variety) is characterized by a more or less distinct combination of inherited morphological, behavioral, physiological traits.

I am blood type O-positive, which I remember by staying 'optimistic positive.'

When I say that human beings are just gene machines, one shouldn't put too much emphasis on the word 'just.' There is a very great deal of complication, and indeed beauty in being a gene machine.

Whereas recessive traits require two bad copies of a gene to become noticeable, a dominant trait expresses itself no matter what the other copy does. A benign example of dominance: If you inherit one gene for sticky wet earwax and one gene for dry earwax, the sticky earwax gene wins out every time.

Scientific careers rely on inheritance, environment, and random events, like all biological phenomena.

The interaction of the variation in our genes is what's responsible for lots of our attributes and vigor.

If A denotes one of the two constant traits, for example, the dominating one, a the recessive, and the Aa the hybrid form in which both are united, then the expression: gives the series for the progeny of plants hybrid in a pair of differing traits.

It is hard to hide our genes completely. However devoted someone may be to the privacy of his genotype, others with enough curiosity and knowledge can draw conclusions from the phenotype he presents and from the traits of his relatives.

For each gene in your genome, you quite often get a different version of that gene from your father and a different version from your mother. We need to study these relationships across a very large number of people.

Identical twins are ideal lab specimens for studying the difference between learned and inherited traits since they come from the womb preloaded with matching genetic operating systems. Any meaningful differences in their behaviors or personalities are thus likely to have been acquired, not innate.

If we speak only of the genotype, I can find a black who, at the level of his chromosomes, is closer to a Swede than Peter Botha is. But what counts in reality is the phenotype. It is the physical appearance which counts. This black, even if on the level of his cells he is closer than Peter Botha, when he is in South Africa he will live in Soweto. Throughout history, it has always been the phenotype which has been at issue; we mustn't lose sight of this fact.
