A simple model for the influence of meiotic conversion tracts on GC content. [PDF]

open access: yesPLoS ONE, 2011
A strong correlation between GC content and recombination rate is observed in many eukaryotes, which is thought to be due to conversion events linked to the repair of meiotic double-strand breaks. In several organisms, the length of conversion tracts has
