Genetics Quotes - Page 2

I may finally call attention to the probability that the association of paternal and maternal chromosomes in pairs and their subsequent separation during the reducing division as indicated above may constitute the physical basis of the Mendelian law of heredity.

First LawIn every animal which has not passed the limit of its development, a more frequent and continuous use of any organ gradually strengthens, develops and enlarges that organ, and gives it a power proportional to the length of time it has been so used; while the permanent disuse of any organ imperceptibly weakens and deteriorates it, and progressively diminishes its functional capacity, until it finally disappears.Second LawAll the acquisitions or losses wrought by nature on individuals, through the influence of the environment in which their race has long been placed, and hence through the influence of the predominant use or permanent disuse of any organ; all these are preserved by reproduction to the new individuals which arise, provided that the acquired modifications are common to both sexes, or at least to the individuals which produce the young.

Every time you understand something, religion becomes less likely. Only with the discovery of the double helix and the ensuing genetic revolution have we had grounds for thinking that the powers held traditionally to be the exclusive property of the gods might one day be ours. . . .

Except for the rare cases of plastid inheritance, the inheritance of all known cofactors can be sufficiently accounted for by the presence of genes in the chromosomes. In a word the cytoplasm may be ignored genetically.

Genes do not make an individual homosexual. They play their part, but so does the rest of the universe.

We both lacked the same thing in our childhoods - the love of a father... We both sought to fill that lack in our adult lives with family and love, as everyone does, but also with thrills and sometimes periods of recklessness. Luckily, I have always come back from my recklessness. Tommy Darling did not.

There were three things sought by invaders who crossed oceans to discover America. Those were gold, gospel, glory. There are four things sought by aliens who crossed heavens to discover planet earth. Those are gold, gospel, glory, gene.

Our highest contribution is making this world peaceful and happy. That comes when we can radiate peace and harmony from every cell, gene and DNA of our body.

The universe is not only stranger than we imagine, it is stranger than we can imagine.

If you want to know if your kid is going to be fast, the best genetic test right now is a stopwatch. Take him to the playground and have him face the other kids.' Foster's point is that, despite the avant-garde allure of genetic testing, gauging speed indirectly is foolish and inaccurate compared with testing it directly - like measuring a man's height by dropping a ball from a roof and using the time it takes to hit him in the head to determine how tall he is. Why not just use a tape measure?

Signal transduction science recognizes that the fate and behavior of an organism is directly linked to its perception of the environment.

The long-lived gene as an evolutionary unit is not any particular physical structure but the textual archival information that is copied on down the generations. [I]t is widely distributed in space among different individuals, and widely distributed in time over many generations. [A] successful gene will be one that does well in the environments provided by these other genes that it is likely to meet in lots of different bodies.
