1 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!

2 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?

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

4 Agenda  Catalyst/HW Review  Quiz  Types of blood  Are you a positive person?  Whiteboards practice  VIDEO GAME PRACTICE  Exit Question

5 Catalyst/Homework Review

6 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: I A, I B, and i.  I A and I B are both dominant (co-dominant).  i is recessive.

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

8 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 A blood has A antigens, and B antibodies. Type B blood has B antigens, and A antibodies. Type AB blood has A and B antigens, and no antibodies Type O blood has no antigens, and A and B antibodies

9 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

10 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

11 It’s time to pretend that we’re…

12 Guided Practice  Bob Dylan’s blood is I A I A, and lacks Rh factor.  What type blood does he have?  Can he receive Type B blood?  Can he receive Type O blood?

13 Guided Practice  D’Angelo’s blood is I B i, and has Rh factor.  What type blood does he have?  Can he receive Type AB blood?  Can he receive Type B blood?

14 Guided Practice  Goapele’s blood is I A I B, and lacks Rh factor.  What type blood does she have?  Can she receive Type B Rh- blood?  Can she receive Type A Rh+ blood?

15 Guided Practice  Dave Grohl’s blood is ii, and has Rh factor.  What type blood does he have?  Can he receive Type O Rh+ blood?  Can he receive Type AB Rh- blood?

16 Guided Practice  Kid Cudi’s blood is I A I A, and lacks Rh factor.  What type blood does he have?  Can he receive Type O Rh- blood?  Can he receive Type AB Rh+ blood?

21 Exit Question  Lil’ Wayne’s blood is I A i, and has Rh factor.  What type blood does he have?  Can he receive Type A Rh- blood?  What will happen if he donates blood to someone who is Type AB Rh-? Write in complete sentences! Don’t talk during the Exit Question!
