The Sickle Cell
The deadly gene
Sickle Cell can not be cured
The sickle cell is a heredity blood disorder that you inherit from your ancestors or ancestor. Sickle cells are red blood cells that are shaped much differently than a normal red blood cell. Red blood cells are usually oval and smooth. Sickle cells are thin and rigid. The shape and texture make these blood cells easy to clot. That is why this heredity disorder is so dangerous and incurable.
How is this natural selection?
Sickle cell is natural selection for a few reasons. Sickle-cell trait is rare in North America with a single exception--African Americans. One in 12 of them carry the sickling allele and about 72,000 have sickle-cell anemia and other related clinical symptoms. One in 375 African American children is homozygous recessive for it. It is more adaptable to African Americans, and that is how it is an example of natural selection.
3 principles of natural selection:
Reproduction
Sickle Cell affects reproduction. It is harder to reproduce with the Sickle Cell and if you do reproduce with the Sickle Cell, your offspring is much more likely to inherit the trait of the Sickle Cell.
Genetic Variation
If a parent contains the Sickle Cell, their offspring(s) are more likely to develop this gene because the parents pass the gene down. If both parents have it, you have a 100 percent chance that you will get it. If one parent has it, you are still capable of getting it, but you still have a chance that you will not get it.
Competition
The sickle cell competes with the normal cell. They are both red blood cells competing to be the majority. The sickle cell is a deformed red blood cell that runs throughout your body. The shape causes them, to clot more which is not good.

What will happen in the future?
The Sickle Cell is extremely dangerous, and this is why. Less blood flow can damage the body's organs, muscles, and bones, sometimes leading to life-threatening conditions. All organs need blood to work, and if there is not enough blood for your organs, they will be very damaged, and your life expectancy will be shorter.
