Generality is fundamental for apomictic survival as clones surviving for many generations could only have done so by virtue of being able to tolerate all environmental variation exposed to since their origin, while more specialized genotypes would have rapidly gone extinct.
We have been serving the public for many generations and only wish to serve for many more years to come.
But Laurent Excoffier, a population geneticist at the University of Bern, says that the team has not entirely ruled out alternative explanations to deliberate inbreeding, such as so-called "founder effects"—in which a small group of people harbor a genetic trait that is retained at high numbers in the population, over many generations, due only to chance.
As noticed already by Mayr (1963), sustained disruptive selection, operating over many generations, is only achieved under highly restrictive and unrealistic conditions in classical population genetical models.
The troubles surrounding Larry Gopnik in suburban Minnesota many generations later can only be seen as the revenge of "Hashem" — the word that Conservative Jews in this Midwestern community use to name God. (If that Old Country dybbuk was not God himself, he must have been in God's employ).
Some studies [ 46– 48] have studied the efficacy of genomic selection when performed over many generations, and where only a few QTL control genetic variation.
One irony among many, of course, was that Aby Warburg, the man who started it all, was able to do so only because his family had, for so many generations, thought that the only way Jews like them could flourish would be if they made lots of money, and could do what they wanted with it.
"These wells have been here for many generations and we have only been doing minor maintenances such as removal of debris and weeding them", says Mama Adam of Mtumba suburb.
"It's not only for this generation but many generations to come.
