There is a chapter 14 exam next week on Tuesday for which students should prepare by studying their notes, worksheets, and lab materials, as well as studying in groups. The document also discusses ABO blood groups, noting there are 3 alleles that determine 8 main blood types based on the presence or absence of A, B, and Rh antigens. Blood types are identified by these antigens, as antibodies will destroy blood cells with non-matching antigens in a transfusion.

1. Week 6 Warm Up
Day 1:

4. studying in a group with friends
Day 2 :
What are the ABO blood groups?
How many alleles are there for the blood gene.
types of blood?
● A+ -- codominant
● A-
● B+
● B-
● AB+
● AB-
● O+
● O-
● IA i or IA IA = A type
● IB i or IB i= B type
● IA IB = AB type
● i i = O type
+,- Rhprotein
+ dominant
- recessive
+ + positive
+ - positive
- - negative
