Transposable element-induced response to artificial selection in Drosophila melanogaster.
The P family of transposable elements in Drosophila melanogaster transpose with exceptionally high frequency when males from P strains carrying multiple copies of these elements are crossed to females from M strains that lack P elements, but with substantially lower frequency in the reciprocal cross. Transposition is associated with enhanced mutation rates, caused by insertion and deletion of P...
متن کاملA novel genetic framework for studying response to artificial selection
Response to selection is fundamental to plant breeding. To gain insight into the genetic basis of response to selection, we propose a new experimental genetic framework allowing for the identification of trait-specific genomic loci underlying population improvement and the characterization of allelic frequency responses at those loci. This is achieved by employing a sampling scheme for recurren...

The founder effect and deleterious genes.
During the rapid growth of a population from a few founders, a single deleterious gene in a founder can attain an appreciable frequency in later generations. A computer simulation, which has the population double itself in early generations, indicates a lethal could attain a frequency of 0.1. Since deleterious recessive genes are eliminated from large populations at a very slow rate, variations...
متن کاملThe founder space race: a response to Waters et al.
assert incorrectly that there is a ‘lack of evidence for causal connections between genetic factors, demography, and extinction risk’ [1]. Their entire Letter provides detailed evidence for this point. Unfortunately, their reply largely overlooks our point that the justifications for the 50 and the 500 in the 50/500 rule are fundamentally different. We are in complete agreement with them that t...
