We reviewed multiple alleles, co/incomplete dominance and sex-linked traits before taking a quiz on it. Then, we dove into dihybrid crosses. We took notes and practiced our skills on a SpongeBob worksheet that was turned in as an exit ticket. If you are having trouble foiling, here are the visuals we referred to in class.
Today, we reviewed genetics and took a SpongeBob Square-pants genetics quiz. After we completed a practice pedigree, we answered the following exit ticket:
1-3. With regard to hemophilia: what are the genotypes of Sophia of Greece, Alexis, and Irene?
4. Can women be hemophilic?
5. Can men be carriers for it?
H = Non-hemophilic
h = Hemophilic
Then, the idea of incomplete and codominance was considered. We reviewed a PowerPoint and a worksheet. This class was used to introduce the topic of special cases in genetics.
Students turned in their homework on Sex-linked traits. A copy of that assignment is here: Sex-linked_Traits_Problems
Next, we used what we learned about pedigrees and sex-linked traits to work on Sex-linked pedigrees. Click here for a copy: Pedigree worksheets (pages 3 and 4 of the pdf file.)
Next, we did a close reading on Genes and Blood Type. from the reading students choose at least five words that they thought were most important and used them to write a summary of what they read. The then created a graphic organizer of their own.
We review the principles of Genes and blood type with this: Blood Typing and Genetics
Finally, we practiced Punnett square problems involving blood types. If students did not finish it was homework: Click Here for a copy of the assignment.
