Sorry. I don't get your point. Assuming 100% mortality, how could there possibly be an advantage if the genes of the afflicted cannot be propagated ?

- tysonzni 9y agoPeople who have sickle cell anemia still have a life expectancy of years (>40 in US). On the other hand, getting malaria usually means you mortality is measured in days not years. Everyone has a "100% mortality" but the window of survival differs between diseases.
- nkozyra 9y agoBecause not every person with the mutation gets sickle cell anemia. There is essentially a genetic burn rate that is less than the fitness imparted via malarial resistance.
