Make a pedigree chart based on the situation Blood Type • Blood type is determined by the presence of several different proteins found on the surface of red blood cells. Blood type A has the A antigens on the surface of red blood cells. Blood type B has the B antigens on the surface of red blood cells. Blood type AB has both A and B antigens. Blood type O has neither. Situation: Guinevere decides to trace the inheritance of her blood type through her family, all the way back to her great-grandmother Natalia. Guinevere's great-grandmother Natalia, has type A blood. Natalia and her husband Claude have five children-three sons, Miguel (who has blood type A), Mark (who has blood type B) and David (who has type AB blood); a daughter (Jane) with type O blood and another daughter (Janella) with type A blood. Jane marries a man and they have two sons (Marco and Polo) who both are blood type A and a daughter (Mara) who has blood type B; Janella on the other hand marries a man and together have three sons (one with blood type A, one with AB, and one with O). Miguel marries a woman with type O blood and together they have three children (daughter Frances and son Albert who both have type A blood, and a son Mike with type O blood). Mike marries Johann and together they have one daughter, Guinevere. Guinevere knows that her parents both have the same blood type, but she has never yet had a blood test to determine her own blood type.
