Claim: Individuals in a population have genetic variations that can be passed on to their offspring. How could an organism's traits influence the survival rate of the population?

If an animal has a certain trait that decreases it's fitness ( i.e. less likely to survive), it can lower the survival rate of that population. Verses a population with a trait that increases fitness ( i.e. More likely to survive) and  would most likely increase the survival rate.
