...decease, be a carrier of the trait, or not be affected at all by it. Someone who has the decease is at great disadvantage and will die a premature death. Someone who is a carrier for the trait will not be very affected by sickle cell but will still be at a disadvantage. If a person who does not have the decease of is a carrier for sickle cell will be normal and have not have any problems at all. With decease like sickle cell anemia we see we see that the decease; because of malaria, which is a mosquito-transmitted infection that affects the red blood cells. Malaria only affects normal blood cells, therefore it has some impact on carriers for sickle cell and it and it has no effect at all on individuals who have the anemia. We see that in places where malaria is present that that trait for sickle cell tends to strive. In other cases where malaria is not a problem we see that the percentage of people who carry the trait for sickle cells decreases. It is hard to know if the trait for sickle cell was something that evolved as an adaptation for malaria or if it was something that originated from a mutation. But it is clear that the sickle cell does serve a purpose in preventing a full-blown infestation of malaria. We can see that the trait for sickle cell is one that now serves a purpose. It is what helps minimize the impact of malaria. People who are homozygous for sickle cell will be at a disadvantage because, even though mal...
