Genetic Diagram Of Sickle Cell Anaemia. Using the example of sickle cell anemia kerry evans simplifies the concepts of single and multi gene traits so that her kids and yours can understand. For example along the left side of the square are the two.
The sickle cells also get stuck in blood vessels blocking blood flow. If one parent has sickle cell trait hbas and the other has sickle cell anaemia hbss there is a one in two 50 chance that any given child will get sickle cell trait and a one in two chance that any given child will get sickle cell anaemia. Signs and symptoms of sickle cell disease usually begin in early.
Sickle cell anemia is a disease in which the body produces abnormally shaped red blood cells that have a crescent or sickle shape.
The gene that can cause sickle cell anemia is called hbb and is located in chromosome 11. The gene that can cause sickle cell anemia is called hbb and is located in chromosome 11. If one parent has sickle cell trait hbas and the other has sickle cell anaemia hbss there is a one in two 50 chance that any given child will get sickle cell trait and a one in two chance that any given child will get sickle cell anaemia. The first diagram only showed the possible genotypes for a child with two parents who are heterozygous for the sickle cell trait.
