To convert poses from DUF to Poser format you could look at Ken's Pose Converter: https://www.renderosity.com/marketplace/products/152558/duf-pose-converter-for-poser-12

If your Genesis figure is Genesis9, with 'A' pose and separate 'twist' joints, you may be out of luck. There was a 'Nova' figure, shaped and posed like G9, with split joints. It appears it was withdrawn from the marketplace. 

Alternative is to convert a G9 from DS. There's some threads about this in the forum, but you may need Poser11 (DSON). DAZ never updated their product.
