See http://forums.kingsnake.com/view.php?id=918203,920474 where some on this has already been covered.
Once a hybrid, it will always be a hybrid. I like to think of it as a bucket of toxin where even one molecule will give you the most horrible death you can imagine. Pour half of it out and refill with pure water. Mix it up. Repeat over and over again. (This is the case where the frog always jumps half way to the end of a log, so he can NEVER make it to the end no matter how long it takes.)
Statistically, you would eventually get down to 2 molecules, then one, then sero just playing the odds. BUT, would you ever risk drinking out of it for a nickel? I doubt it....lol.
The point being, thanks to crossovers, introns, etc. you are NOY inheriting a "package" of chromosomes. The chromosomes get mixed up. It's VERY common, but I don't know the exact frequency. Pretty dang high enough.
You all know what linked genes are, correct? Well, it is so common that genes on the same chromosome but FAR apart can almost be considered to NOT be linked and inherited separately. (so I've been taught, but I still scratch myself wondering HOW? when I think about it.....lol.) That makes it pretty darn common, dontcha think?
Anyway, back to topic on hand. Produce a hybrid and bred the babies together for a generation or three. You are likely to not have a SINGLE cromosome in ANY of those Fx generation offspring that have a chromosome that is pure one species or another thanks to the above mentioned reasons among many others.
BYW, I don't follow this forum - a link was referred to me. Sooooo, I might not check back to read replies, etc. None of the above is a weak possibility - it's a watered-down version of the best theories/hypothesis the guys that work with that stuff have figured out.
