Me too. I'm stumped.

I get why amphidiploid / allotetraploid roses are fertile. The way I see it, those chromosomes have no choice as to which to pair up with.

I have no idea which chromosomes pair up and swap genetic material in typical tetraploid roses.
Given 7 sets of four how many combinations are there? I think 2,187 possible pairings - that math needs checking.

I'm not smart enough to explain it, but I believe this is why really good, fertile triploids, have been, and will be, important going forward.
