I don't know an answer, but you might find it useful to ask the question on the Quora.com website. If you have any difficulty I could ask it for you there. I see the other answer here is a bit old, though not necessarily too old.
By the way, most people only have one genome. Claiming to have two appears to be arrogant!
It would truly be of so kind of you on the off chance that you share this to Quora!
Well, I have those two genomes not inside my nucleus, but stored in my PC! Additionally, if you are unsure about the existence of any organisms, you know, most the higher living beings are now referred as metaorganism! In a sense, all of these organisms are bearing multiple nested genomes within their own large genome!
