Can you explain what evolutionary advantage mean and how it accounts for why sickle cell anaemia is still so widespread in Africa?
evolutionary advantage means that if you have to types of sickle cell anaemia and one is resistant to a drug the the other one is not then the one that is not resistant dies off and the sickle cell anaemia that is resistant becomes dominant and that is why sickle cell anaemia is still so widespread in Africa because the strain that is widespread in Africa is resistant is anti-biotics.
Why are people with sickle cell trait resistant to malaria?
Not sure if this is right but could it be because the blood cell does not contain enough oxygen for the parasite to survive?
What is a heterozygous phenotype?
Having different alleles at one or more corresponding chromosomal loci. Like people who are resistant to sickle-cell anaemia.
