Genesis is usually the Daz Studio weight mapped figure, which is not natively supported in Poser. The official way to get Genesis (or Genesis 2) into Poser was the DSON Importer for Poser, but that required an older version of Poser than is in the current Poser build, and I would assume the same is true for Poser 13 (which means that the importer is no longer avaiiable).
