The probability of having a child having sickle cell anemia can be obtained form Mendelian genetics.

Sickle cell anemia (SCA) is a human genetic disorder that causes the red blood cells to be sickle shaped leading to the clotting of blood in the sufferers and frequent health crisis.

If one parents do not have the disorder but each has one parent that has the disorder, then it follows that each parent has the recessive allele and there is a 25% percent chance that their child could have the disorder.

If the man is affected by the disorder and the woman has no family history of the disorder, then there is a zero percent chance of having a child with the disorder.
