Behaviour does not influence genes. At least not directly; You keep
the genes you are born with for life. Until genetics was properly
understood it was thought that aquired characteristics could somehow
feed back into what was then called the germplasm.(So if a
blacksmith developed big muscles his son would inherit them.) This
view is most associated with the early French evolutionist J B
Lamarck, but even Darwin considered that this might be happening.
But if you mean that some innate behaviour might lead us not to pass
on our genes to the next generation, then I agree that this could
indeed be the case. If it were to be shown that this was happening
consistently so that the genes that predisposed any particular
behaviour were being gradually being removed from the gene pool then
there is a word for that it is "evolution". Whoever could show this
to be happening would be able to prove that mankind is still
