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?

KEY

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.

Punnet Squares and Test-Crosses 4/26- 4/27/16

Today, we worked on test-crosses and statistical analysis of phenotypes and genotypes using Punnet squares. There was a warm-up about cat test-crossing, this worksheet can be found on the make-up work counter along with the penny lab that we completed for a stamp. The directions for the exit ticket for this lesson can be found in the image below. The worksheet the exit ticket was completed on is also on the counter in class.

We were able to discuss pedigrees briefly. Below is the example discussed in class, along with information on how to read them.

Genetics 4/24/-4/25/17

Today, we completed a genetics smiley face warm-up and took notes from this genetics PowerPoint. We talked a lot about the Austrian monk, Gregor Mendel, who is known as the father of genetics.

Then, we worked through a genetics worksheet as a class for an additional stamp. Our exit ticket was a worksheet with four questions that tested punnett square skills based on the day’s lesson.

B Day Classes for 4/8

There will be a quiz  on Tuesday 4/12 covering pedigrees, sex-linked traits, sex-linked pedigrees and blood types. Today, we played  kahoot and quizizz  games to review.

Before the review, we learned about and practiced dihybrid crosses. For a video, on how to do dihydrid crosses, Click Here.

The class practice and note sheet is here: dihybrid_guinea_pigs

The assignment is here: bikini bottom dihybrid crosses

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.

If you need a review of help on blood type genetics, i recommend you watch this video.
