Awesome question, and a post that I've been meaning to create for some time. Tony I don't think enough research has been performed to address the questions regarding inherited traits of BRES - RBG hybrids - but maybe we can work together to advance the research efforts.
Let me add a few for our experts they can hopefully address:
Does gender of parentage species play a factor on genes inherited?
After several generations of interbreeding, will subsequent generations adopt more BG or RES traits? [HBG following several generations of interbreeding assume GSF traits - what about BRES-RBG?]
