DESCRIPTION:Speaker: Denis Roze\nhosted by Nick Barton\nAbstract: Transposa
 ble elements (TEs) are ubiquitous among eukaryotes\, constituting an impor
 tant fraction of the genome of most species. TE insertion is believed to b
 e generally neutral or deleterious\, due to the disruption of gene functio
 n or regulatory sequence\, or to the possibility of ectopic recombination 
 leading to chromosomal rearrangements. This load of TEs may have important
  consequences on various evolutionary processes\, including the evolution 
 of recombination. Using a combination of analytical and simulation results
 \, I will show that the transposition process generates an excess variance
  (positive linkage disequilibria) in the number of TEs per genome even in 
 the presence of negative epistasis (that may stem from the possibility of 
 ectopic recombination). While this excess variance remains small in random
 ly mating populations\, it may become important as the rate of sex or outc
 rossing decreases. Consequences for the evolution of recombination will be
  discussed.
