Nonparadoxical evolutionary stability of the recombination initiation landscape in yeast

Recombination: The birds and the yeast Apes and mice have a specific gene, PRDM9 , that is associated with genomic regions with high rates of recombination, called hotspots. In species with PRDM9 , hotspots move rapidly within the genome, varying among populations and closely related species (see the Perspective by Lichten). To investigate recombination hotspots in species lacking PRDM9 , Singhal et al. examined bird genomes, which lack a PRDM9...
