Question

Why people with sickle cell trait have resistance to malaria parasite

Answer 1

Answer:

People develop sickle-cell disease, a condition in which the red blood cells are abnormally shaped, if they inherit two faulty copies of the gene for the oxygen-carrying protein haemoglobin. The faulty gene persists because even carrying one copy of it confers some resistance to malaria.

Hope it helps.

Answer 2

Sickle Cell develops resistance to malaria parasite:

Step by step explanation:

1) It has been studied that the patients suffering from sickle cell trait tends to develop a condition where the red blood cells are abnormally shaped and they are unable to carry hemoglobin  induced oxygen molecules.

2) The sickle cell patients infected with Plasmodium falciparum tend to collapse and thereby prevent the parasite from entering the individual cell's actin proteins.

Hence, this induces the host to develop resistance against malaria.
