Sickle cell anemia develops as a result of a genetic mutation in the hemoglobin gene. This mutation causes the production of abnormal hemoglobin, known as hemoglobin S, which can cause red blood cells to become sickle-shaped. These sickle-shaped cells are less flexible and can block blood flow, leading to various complications such as pain, anemia, and organ damage. Sickle cell anemia is an inherited condition, meaning it is passed down from parents to their children. **

Sickle cell anemia is inherited in an autosomal recessive pattern, meaning that a person must inherit two copies of the mutated gene (one from each parent) in order to have the disease. If both parents are carriers of the sickle cell trait, there is a 25% chance with each pregnancy that their child will have sickle cell anemia. If only one parent is a carrier, there is a 50% chance that their child will inherit the trait. **

Yes, sickle cell anemia can provide some protection against malaria. This is because individuals with sickle cell anemia have abnormal hemoglobin that can make it more difficult for the malaria parasite to survive and replicate within their red blood cells. As a result, people with sickle cell anemia are less likely to develop severe forms of malaria. However, it's important to note that having sickle cell anemia also comes with its own set of health challenges and complications, so the protection against malaria should not be seen as a benefit of the condition. **

The hammer and sickle symbol is allowed in many countries because it is a widely recognized symbol of communism and socialist movements. While it may be associated with controversial political ideologies, it is also seen as a symbol of resistance, workers' rights, and the struggle for social justice by those who support these ideologies. In many democratic societies, freedom of expression and the right to display political symbols are protected, even if they are contentious or divisive. Therefore, the hammer and sickle symbol is allowed as a form of political expression and representation of certain political beliefs. **
