When Ashleigh inquired about her family's medical history, she found out that Uncle Albert's mother (Ashleigh's grandmother) also had sickle cell disease, but Uncle Allbert's father did not. One of her uncle's six children also had the disease. However, Ashleigh's father, who is Albert's only sibling, did not have sickle cell disease, nor did Ashleigh's mother. Ashleigh's two siblings showed no signs of the disease either. What pattern of heredity does the sickle cell trait follow? Cite evidence from your textbook and its clues to support your conclusion. Based on your answer to this question, what can you conclude about the inheritance of sickle cell disease in Ashleigh's family? What might be Ashleigh's chances of being a carrier of the sickle cell trait?
