So, a middle school science class is learning about genetics and the students are working with recessive and dominant eye colors in punnett squares. A few minutes into the activity one student beckons the teacher over. He has a very concerned look on his face. The teacher is a little worried. This has happened before. Every once in a while a student realizes that he is adopted or his dad isn't who he thought. The teacher hesitantly walks over to the concerned student, ready to have a difficult conversation. ""Do you have a question about the assignment?"" the teacher asks. ""Well,"" the student replies, ""I think I might be adopted, because I have blue eyes and both my moms have brown eyes!"" [According to a Special Ed teacher at my school, this really happened to her.]
