The Colin Leslie Dean species paradox

[biohazard]

Not with the banana. The bird's got it :'(

Maybe with XXX-rays?

I know, bad joke!

Here's a question:

I know the iris is actually a genus, and there are many species of irises. I would assume you can cross different species of irises, that's how we got all the variations. But can you cross an iris with a rose? If not, what is their theory on this.

The reason I ask is I grew up around farms in the midwest, and worked in a corn seed company for a while (quite interesting, we actually did the field work of self and cross-pollination). But the corn never pollinated the soy beans or the alfalfa just across the road, though the pollen would have traveled to them.

Well, if a banana can mate with a bird . . .

I'm not an expert on pollination but I believe that beyond their "pollination syndrome" plants have chemical signaling pathways that prevent intra-generic pollination (ie rose pollen lands on iris stigma - nothing happens).

On a side note: In my part of the world, the wild irises hybridize so commonly it can be infuriating (impossible) to try to key them to species.

I must admit I love to see AFJ's posts here despite the fact that we disagree with most of the stuff. When compared to this gamila-spambot you can really see the difference between an intelligent person and a dimwit repeating himself over and over again without contributing anything into the ongoing debate. Luckily retardness is not contagious, else gamila might cause a real bad epidemic...

Gamila, Dean's paradox has already been resolved in my post about changing the wavelength of a light ray, but you have refused to answer it.

wavelength is not a bird

That's not the point and you know it.
