Inheritance of Sickle Cell Anaemia
Could my Children get Sickle Cell Anaemia? You may find the following diagrams useful to help you understand how sickle haemoglobin is inherited. In all the following diagrams you will get the same possibilities if the genes in the mother and father are swapped over.
The following pedigree traces sickle cell disease through four generations of a family living in the highlands of eastern Africa. Use the pedigree to answer the following questions.
