Bigeneric/intergeneric vs. interspecific
So I was looking up the term Ã¢ÂÂinterspecific hybridÃ¢ÂÂ awhile back and a couple sites commented that it doesnÃ¢ÂÂt always have to be two species within the same genera, but different species of different genera. WouldnÃ¢ÂÂt that make it a bigeneric/intergeneric plant though?! Or do you apply both terms to such a plant, meaning if the offspring was a result of crossing two species of different genera it would be a bigeneric AND interspecific hybrid?
Since I am here... what is the reason some genera and/or species can cross and others canÃ¢ÂÂt?? Is it Chromosome compatibility or something? IÃ¢ÂÂm not knowledgeable in this area whatsoever, so the more dumbed-down the answer the better, lol. ;-)
