Sickle cell anemia is an example of codominance in humans. If a person is homozygous for H'H", he or she is able to
produce normal red blood cells. Those individuals homozygous for HH produce red blood cells that are "sickled".
The cells are unable to carry oxygen properly and severe anemia results. The heterozygous H'H' condition is known
as sickle cell trait". This person usually has no clinical symptoms because he or she is able to produce enough
"normal" red blood cells to function normally.
5. Suppose that a man homozygous for the sickle cell trait has a child with a woman who is heterozygous for this
disease.

What is the probability that the children of this match will develop sickle cell anemia?
What is the probability they will have a child that has the sickle cell trait?
