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.


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.

A day Classes for 4/15

Block 1 College Prep Biology

Studied Sex-Linked Traits. For a review of the powerpoint, click here:  Sex-linked_Traits

We then practiced predicting sex-linked traits. For a copy of that, click here: Sex-linked_Traits_Problems

We then looked at tracing sex-linked traits using a pedigree. Click Here: Pedigree worksheets (Do page numbers 3 and 4)

Block 4A

We reviewed the basic principles of genetics. If you are struggling or need a review, click here. We will have a another quiz on Thursday 4/7.

Next, did a lab to determine the accuracy  of Punnett squares. The link for that is here.

It can be completed with a couple of coins.

B Day Classes 4/4/16

Welcome back from Spring Break! Today, we learned how to read pedigree charts to track traits through generations, then we learned how use Punnett squares to predict Sex-linked traits.
