May 8th and 9th: Special Cases in Genetics Quiz and Dihybrid Crosses

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.foilPpGgFOIL


4/28/17 and 5/1/17 Genetics Quiz and Pedigrees

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.

B Day Classes for 4/6

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.
