sentence: Rapid evolution is supposed to be facilitated by internal repeats , such as within the EPA genes , and by subtelomeric location , situations which enhance recombination frequency and generate new alleles and possibly new genes.Our data firmly support the existence of the Nakaseomyces genus , but nonetheless , two of the species , C. castellii and N. bacillisporus , have diverged in many ways , first by the low conservation of their orthologous genes , when compared to the four other Nakaseomyces , and also by their paucity of tandems , and by their frequent variation in gene numbers compared to the ‘ glabrata group ’ ( such as in “ ohnologous ” ribosomal protein gene pairs ) .
