Are people with Hemophilia prevented of getting Malaria?
No, hemophilia does not confer an advantage against malaria. People with sickle-cell anemia do have an immunity, of sorts.
People who are heterozygous for sickle cells disease are generally healthy because?
They are protected from malaria but don't have the actual disease, although they can still pass it on to their offspring
How is sickle-cell disease a representation of codominance?
It's not sickle-cell itself, but rather being a heterozygous carrier of the disease. People with one dominant and one recessive allele for the disease are immune to malaria without the crippling effects of having sickle-cell anemia. I don't think that it can even represent codominance, though.
What is a heterozygous phenotype?
Having different alleles at one or more corresponding chromosomal loci. Like people who are resistant to sickle-cell anaemia.
Is malaria harmful?
Yes it is. Malaria has killed many people.
How many people in north America get malaria?
You do not have malaria in US. Only immigrants can get malaria, which can come out of the liver.
How did the Greeks stop the spread of malaria?
they pooed on all people with malaria
How can you use malaria in a sentence?
In Africa many people died from malaria.
What is the symbiotic relationship between people and malaria?
the symbiotic relationship between malaria and people is parasitism
What do you think people with malaria often have jaundice?
People with Malaria often have Jaundice because the destruction of the red blood cells that Malaria cause's can cause Jaundice.
Are people with sickle cell anemia resistant to malaria?
No they are generally resistant to malaria
Why a person having malarial parasite does not shows symptoms of disease?
Some peoples (ie tribes/families) who have lived in malaria infested regions have developed a natural partial immunity to the parasite (by a process of natural selection and evolution) such people may be infected by the parasite but do not develop full blown malaria because their immune system keeps the parasite in check.Note, the danger in this is that such people act as the source of malaria affecting others. The mosquito has to bite someone with malaria FIRST then go on to bite a SECOND person. This gives malaria to the SECOND person. Obviously people carrying the malaria parasite but not ill do not go and get treated for malaria (have the parasite in their bodies killed). They therefore act as a hidden reservoir for infection.
