#SickleCellAwareness today. I just wanted to remind you while looking for your life mate that:

AA + AA =✅
AA + AS =✅
AA + SS =✅
AA + AC =✅
AS + AS =❌
AS + SS =❌
AS + AC =❌
AC + SS =❌
SS + SS =❌
SC + AS =❌

Nigeria reportedly has the highest number of people with SS
For those asking, the haemoglobin C gene is also an abnormal gene, just like the S gene

If a person inherits this gene from both parents that person will have Hemoglobin C disease

If the person inherits it from only one parent then the person has the Hemoglobin C trait(AC)
Sometimes it happens also one parent has the S gene, and the other has the C gene, the baby might inherit both and have the sickle cell Hemoglobin C disease (SC)

This disease has similar symptoms similar to sickle cell anemia or Hemoglobin C disease,also said to be less severe
