Reflection: Student Ownership Dihybrid Crosses Are Twice The Fun! - Section 3: Guided Practice - FOIL For Fun!


As I reflect on the dihybrid cross lesson, I have found that the students who struggle with the concept also struggle with their organization and handwriting.  I tell the students ahead of time that the most difficult aspect of dihybrid crosses in my opinion is my inability to read my own handwriting at times.  I warn my students not to be stingy on their paper consumption and make sure each dihybrid cross uses a full 1/2 sheet of notebook paper.  The students seem to enjoy that I expose a teacher weakness by confessing that I cannot read my own handwriting!  This serves as a warning to promote success, as well as a comic relief for the students.

Dihybrid Crosses Are Twice The Fun!

Unit 10: Introduction to Genetics
Lesson 11 of 13

Objective: SWBAT analyze key concepts in genetics as they utilize probability to determine the variations in the genetic outcomes of this activity. Students will create Punnett squares to predict the probability of the given trait variations expressed in a population.

Big Idea: Why stop with one trait when you can examine two? Students will flex their genetics' muscles as they tackle these complex crosses to determine the probability of the outcomes.
