It has temporarily increased, so disadvantageous traits are less lIkely to be passed on.
It has temporarily increased, so disadvantageous traits are more likely to be passed on.
It has temporarily decreased, so disadvantageous traits are less likely to be passed on
It has temporarly decreased, so disadvantageous traits are more likely to be passed on.
