LO: I can investigate Non-Mendelian Inheritance to identify and explain blood types using a virtual lab.

Do Now: What do you already know about blood typing and what do you want to know?

Blood typing is necessary for people who need transfusions because the wrong blood type can cause complication.

Why do people have different blood types?

Vocabulary: Codominance Incomplete Dominance Polygenic Inheritance Epistasis

Genotype Type A = AA or AO Type B = BB or BO Type AB = AB Type O = OO

Why is O the “universal donor?

Type O has neither antigen A nor B to attack external blood. Type AB has no antibodies in plasma, so they can accept any blood type.

Rh Factor A person can be either Rh + or Rh - (Positive is dominant)

Erythroblastosis Fetalis If the father has a different Rh Factor than the mother, the mother will need to take a drug to prevent damage to fetal red blood cells.

Practice Question A women with a type A blood is married to a man with type AB blood, what are ALL the blood types possible among their children?

AA, AO, AB, BO
