From clonal to sexual: a step in T. congolense evolution?
Although clearly demonstrated in Trypanosoma brucei, genetic exchange remains controversial in other trypanosome species. Recently, Morrison and co-workers applied a population-genetics analysis, and established the existence of mating in Trypanosoma congolense. Starting from this original discovery, we focus here on the important question of how mating is induced during the trypanosome life cycle and discuss the use of statistics to evidence this type of non-obligatory biological process.
