Eh? What is the difference between that 'changed' to give RR resistance,
and a gene added to give RR resistance?

Where it came from and how,

I didn't ask you where it came from, I asked what was the difference in
effect.

an unnatural source

It wasn't unnatural, it was a natural mutation.

that I am not yet sure
"Nature" can always cope with in it's normal way.

Why not, nature has been coping with mutations for 1,000,000,000 years.
How much more evidence do you want?

BY the way I notice you avoid answering these questions, I presume
because you have no answer to them.

From your replies I
understand you are sure. So we will have to differ on that.

I see. 1B years worth of evidence isn't good enough for you.

Doubling of genes is not at all unheard of, in fact it's quite common.

And you don't seem to get to grips with the fact that around 999999
out of 1000000 natural mutations are deleterious and most of them are
removed by selection in subsequent generations.

Will that happen with GM then? No,

Yes. It's a gene like any other.
Only continual selection keeps the genes as you want them for a crop
plant.

Being GM crops (or any crops) these genes will not be allowed to disappear
by natural selection will they. So your comment was irrevelent.

1) I notice you are evading the question.
2) To allow crop genes to disappear is trivial. Simply stop growing the
crop.

With regard to any escaped GM genes, they could die out or quite the
reverse, they could make the wild plant more suited to it's environment and
the one with the GM gene would then start to take over ousting the original
plant.

Quite, and the mechanism is pretty obvious and I already explained it.
Now you explain what scenario in nature makes rr-genes successful in the
wild (that is outside a farmed field).

That's one of the old worries about GM.

Only by those who know nothing about nature.

No doubt the GM scientists
are watching those wild Parsley plants in France with great interest.

I await you posting the details.
