Rubbish. That is what engineering is all about. If the observations
don't match the theory, then it has either been improperly applied, or
they change the theory. Usually an estimation or measurement is wrong.

There is a lot of trial
and error and practical theories are continually improved.

That's better

Moving the parts on a computer motherboard might stop it from being so
fast, or make it unstable. Just electric network theory may be severely
lacking.

You mean motherboards don't follow the rules of physics?

When you introduce a gene you also introduce a promoter and the process is
a bit hit and miss.

But nowhere near as hit and miss as mutagens or cross pollination.

It has been found that the characterization of Rounup
Ready soy was rather inexact.

But nowhere near as inexact as trying the results of mutagen
applications, or cross pollinating.

The promoter, when strong, may not just
switch on the gene next to it, but also ones further along.

Just like is happening every second of every day in uncountable
millions of living cells.

And it may not
do that until certain conditions of stress come up. Heat, drought, cold,
other herbicides or pesticides which are later found necessary.

No, the cell that hasn't got the survival mutation dies, and the one
that does survives.

The
theories are not good enough to predict it all.

But nowhere near as hit and miss as mutagens or cross pollination.
