4/21 & 4/24

Today, we started class with some time to make sure everyone had finished their Punnett Square quiz, as well as their "I am me..." poem entry into their portfolio that we had begun the previous class. We are requiring that every student get a 100% on their quiz so that as we go on to talk about more complex genetic inheritance patterns, we can make sure that everyone is starting off with a solid understanding of the basics.  I am me Poem

Following this, students did an activity where we lined up by height. We graphed our data to show that height is considered a "continuous trait" and is not a "binary" trait. Most of the genetic traits we have been looking at have been presented as binary. You have blue eyes or brown eyes, can roll your tongue or can't roll your tongue.  In real life, most genetic traits (including these examples) exist more on a spectrum. As a group, students brainstormed a list of traits that might exist on a spectrum and are not binary traits.

For the last part of class, we learned about two more genetic inheritance patterns, Incomplete Dominance & Co-dominance, that start to explain how genetic traits exist beyond the binary. Students took lecture notes, then worked on practice problems.
