March 13/14

Bell Ringer: In humans blood types can be O (OO), B(BO or BB), A(AO or AA), or AB(AB).  If a boy with AB blood type has a sister with O blood type, what will the parents genotypes be?  What type of inheritance is this?
Next we reviewed pedigrees as a class and then we took notes on mutations.  See chapter 12 in your textbook to finish filling in your genetics notes.  Last of all, students began working on 3 generation pedigrees.
