It's because Sickle Cell is a recessive trait.

No, Tiki Barber does not have sickle cell disease. He is a retired NFL player who has been very active in various charitable causes, but sickle cell disease is not one of the health conditions he has publicly discussed.
If you carry the sickle cell gene, it doesn't really mean much as far as your own personal health goes. Except that you are less likely to get malaria. However, if you decide to have kids, and whoever you mate with also carries the sickle cell gene (not the full blown disease/gene) , your child has a chance of having sickle cell disease (full blown).
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.

Sickle cell anemia is a disease passed down through families in which red blood cells form an abnormal crescent shape. It is also called sickle cell anemia.
No, sickle cell disease is not cancerous.
No. Sickle Cell is not an infectious disease, but is genetic.

sickle cell disease
Sickle cell disease is a genetic condition that a child inherits from their parents, and symptoms typically manifest in early childhood. A child cannot "get" sickle cell disease at the age of sixteen if they do not already have the genetic traits for it. However, if a person has the sickle cell trait, they may not show symptoms until later in life, but the underlying genetic condition is present from birth. Therefore, a child diagnosed with sickle cell disease at sixteen would have had it since birth, but symptoms may not have appeared until later.
What is sickle cell disease?Sickle cell disease is an inherited disorder that affects red blood cells. People with sickle cell disease have red blood cells that become hard and pointed instead of soft and round. Sickle cells cause anemia, pain and many other problems.Top2) What is sickle cell trait?If you have sickle cell trait, you have inherited the gene for sickle cell disease. Sickle cell trait does not turn into sickle cell disease. If someone has sickle cell trait and his partner has sickle cell trait they may produce a child with sickle cell disease. There are about 2.5 million people in America with sickle cell trait.Top3) If sickle cell trait is not an illness, why are people tested?Babies are tested to see if they have sickle cell disease. Teens and adults are tested mainly to see if they can have a baby with the disease.Top4) What medical problems are caused by sickle cell disease?Lung tissue damage, pain episodes and stroke. The blockage of blood flow caused by sickled cells also causes damage to most organs including the spleen, kidneys and liver.Top5) How many people have sickle cell disease?Sickle cell disease is a global health problem. In the United States it is estimated that over 70,000 people have sickle cell disease. About 1,000 babies are born with the disease each year in America.Top6) How long does a person with sickle cell disease live?The average life expectancy in America has improved. It is now in the mid 40 years of age range.Top7) Are people of African descent the only group affected?No. It is also present in Portuguese, Spanish, French Corsicans, Sardinians, Sicilians, mainland Italians, Greeks, Turks and Cypriots. Sickle cell disease also appears in Middle Eastern countries and Asia.Top8) Is there a cure?There is no universal cure for sickle cell disease. Research in gene therapy, the ultimate universal cure, is currently underway.Top9) What are some promising treatment developments?The use of hydroxyurea has shown promising results on some adult sickle cell patients. It reduces the frequency of severe pain, acute chest syndrome and the need for blood transfusions.Top10) Can people with sickle cell disease live a productive life?Yes. But like all patients with chronic disease, sickle cell patients are best managed in a comprehensive multi-disciplinary program of care and a strong extended support system.
Yes, Sickle Cell-Anemia is a genetic condition that is passed down from one generation to the other.
in sickle cell trait you don't actually have the disease. you are only able to pass the disease to your kids if you marry a person with sickle cell or that also has the trait. sickle cell disease is when you actually have the disease. you can pass it to your kids if you marry someone with the trait or the disease. if you marry someone without a trait or disease then your kids will most likely have the trait.
The sickle cell anaemia is not a deficiency disease. It is a hereditary disease caused by defective gene in both the parents.
