Exchange of breeding individuals between two populations tends to homogenize their gene pools. — © Peter R. Grant
Exchange of breeding individuals between two populations tends to homogenize their gene pools.
New gene pools are generated in every generation, and evolution takes place because the successful individuals produced by these gene pools give rise to the next generation.
A final agreement between Israel and the Palestinians has to be based on a program of exchange of territory and populations.
As a consequence, geneticists described evolution simply as a change in gene frequencies in populations, totally ignoring the fact that evolution consists of the two simultaneous but quite separate phenomena of adaptation and diversification.
I think that my main criticism in that book was directed at the general assumption that adaptation characterizes populations and species, rather than simply the individuals in the populations and species.
I'm always very interested in breeding. Raising cacti is breeding. My lotus plant collection is breeding. The insects are breeding.
Thought tends to collect in pools.
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.
The lower classes are such fools. They waste their money on the pools. I bet, of course, but that's misleading. One must encourage bloodstock breeding.
Those bearing the heavy responsibility of caring for captive gorillas should be encouraged to exchange so-called nonbreeders between populations, an inherent process among free-living gorillas and one that avoids inbreeding and also stimulates productivity.
The essence of peace is to merge two opposites. Therefore your notions should not scare you if you see another, who absolutely opposes you, and you presume that there is no chance for peace between you two. On the same token when you see two individuals who are exactly two opposites, never say it would be impossible for them to reconcile. On the contrary, and this is the perfection of peace to make it between two opposites.
People who criticize The Selfish Gene like that often haven't read it. The selfish gene accounts for altruism toward kin and individuals who might be in a position to reciprocate your altruism.
No one but Gene Tierney could have played 'Laura.' There was no other actress around with her particular combination of beauty, breeding, and mystery.
Every relationship between two individuals or two groups will be characterized by the ratio of secrecy that is involved in it.
The reduced variability of small populations is not always due to accidental gene loss, but sometimes to the fact that the entire population was started by a single pair or by a single fertilized female. These 'founders' of the population carried with them only a very small proportion of the variability of the parent population. This 'founder' principle sometimes explains even the uniformity of rather large populations, particularly if they are well isolated and near the borders of the range of the species.
True intimacy, the exchange of affection between two people who are not lying, is transforming.
I knew the ribosome was going to be the focus of Nobel prizes. It stands at the crossroads of biology, between the gene and what comes out of the gene. But I had convinced myself I was not going to be a winner.
