Biology: February 12 and 13 - Mendel and Basic Punnett Squares

First we corrected our essays from last unit since so many people did poorly
Then we looked at several of the traits people had in our class (like attached earlobes, dimples, freckles, and hitchhiker’s thumb)
Then we took notes on Mendel - the guy who got genetics started
Then we talked about the upcoming Family Trait Survey homework

The Family trait survey requires students to pick a recessive trait (like attached earlobes, long big toe, red hair, blond hair, hitchhiker’s thumb, no chin cleft, straight hairline, non-tongue roller, straight little finger, or blond hair) and figure out who in their family has that trait. They need three generations of data. That means everyone’s names in one generation, everyone’s relationships, and whether or not everyone has a trait. It is going to be a big project so they need as many names as they can get. Grandparents, uncles, aunts, cousins, siblings. Then they need a parent’s signature to show that they gathered the data.

You need to fill out the notes and come in to be sure you understand how to use a punnett square
