Fig. 7From: Ruminant-specific multiple duplication events of PRDM9 before speciationProposed model of PRDM9 evolution in ruminants. The proposed model is based on the evidence of gene duplication, inter-species and within species gene conversion, speciation and divergence time, as well as the evidence of variable selection pressures at the N- and C-terminal regions of the PRDM9Back to article page
