Blood Typing Catalyst: In camels, having a large hump is dominant over having a small hump. Create a Punnett square to show the potential offspring of a heterozygous camel and a camel with a small hump. Make sure to list the genotype and phenotype percentages! Write in complete sentences! Don’t talk during the Catalyst!

Have you ever wondered… Why we have different types of blood? Why could you die if you get a transfusion of the wrong type of blood?

Objectives By the end of today, SWBAT… Identify blood type genotypes and phenotypes Determine the correct type of blood to transfuse into a patient

Catalyst/Homework Review

Blood Typing Sometimes there are more than two alleles for a trait. The most important case for you to learn about is… blood type! Key Point #1: Blood type has three alleles: IA, IB, and i. IA and IB are both dominant (co-dominant). i is recessive.

Since IA and IB are both dominant, they are expressed at the SAME TIME Types of blood IA and IB are co-dominant IA IA = Type A IB IB = Type B IA IB = Type AB i is recessive IA i = Type A IB i = Type B i i = Type O Since IA and IB are both dominant, they are expressed at the SAME TIME

Antigens and Antibodies Key Point #2: Antigens determine blood type. Antibodies attack antigens. If you receive the wrong type of blood, your antibodies will attack the new antigens, causing blood cells to clump and crack. Type O blood has no antigens, and A and B antibodies Type AB blood has A and B antigens, and no antibodies Type A blood has A antigens, and B antibodies. Type B blood has B antigens, and A antibodies.

Positive or Negative Key Point #3: Rhesus factor determines if your blood type is positive or negative If you have Rh factor, your blood is positive If you lack the Rh factor, your blood is negative

Whiteboards For each problem… Determine the blood type Determine if the person can receive the transfusion If the person CANNOT receive the transfusion, explain what will happen if the wrong type blood is given to them
