If R is measured in ohms and G is measured in siemans (or mhos) how can
you say one of them is much larger than the other?

Sorry, I should have said (effect of R) (effect of G)
on the losses. Or 0.1 ohms/meter in series has a greater
effect than 1/(0.9 micromhos/meter) in parallel. That's
about 7 magnitudes difference based on an example in
"Transmission Lines" by Chipman.
