Re: HYB: question - probability inheritance of rebloom

Thanks Mike. I had been assuming that was the case, but realized I'd never thought to ask (or have forgotten if I did!)
What I'm really wondering is what percentage of rebloom I can hope for crossing (for example) non-reblooming step siblings from IMMORTALITY, where both other parents are non-rebloomers.
Would it be one in four, one in six, one in a zillion (several, one or two, none)? 

Assuming there isn't anything in the non-reblooming line to 'block' rebloom.
For example, [to pick a potential real example] what percentage of seedlings might be expected to be rebloomers (here) from a cross like this: (IMMORTALITY x CELEBRATION SONG) X (IMMORTALITY x RING AROUND ROSIE)?
Both CSONG and RAR have been reported to rebloom elsewhere sometimes, but not in my climate.
Only 2 tenths of an inch of rain from that last 'storm', but every drop counts!
