We continued our work with pedigrees today working on problems in partners and individually. Use the video to the right to review pedigree analysis. The genetics unit exam will be Monday September 30. 

This week we will be learning about pedigrees. We went over the basics in class today. Watch or rewatch the video to the right to learn how do draw a pedigree, which is just a family tree that's used to track a single trait.

In class today we extracted DNA from strawberries. You can do this experiment again at home too. Check out the video to the right to see how this experiment works.

Gold Tape Question: Strawberries are Octoploid meaning they have 8 copies of their DNA in every cell which makes them great for DNA extraction. There is another common fruit that is used in this experiment as well that is hexaploid. What is the fruit and what does it mean to be hexaploid? (Hint: The fruit is green)

Today we learned about two new types of genetics, Incomplete dominance and CoDominance. Both of the types of genetics will be on the quiz Tuesday. Watch the video to the right to review both concepts.

​Double Gold Tape Weekend!
Fold your Origami DNA and bring it to Mr. Powell for some gold tape. Use the video to the left as a guide.

Question: What kind of dominance is expressed in human blood types? Explain your answer (you must write at least a two sentence explanation)

Today we learned how to create Punnett squares. Watch the video to the right to see an animated version of this powerful genetics technique. We also started working on some independent Punnett square work with our good friend Spongebob Squarepants.
