    Hello Mary Poffenroth;
    When you spoke about the punnet square at 1:16, my intelligence made me realize that you told us to draw a line from the top to the bottom, and then another line from left to right.
    My question is: in the hypothetical case i drew the line from RIGHT to LEFT, would it be wrong?
    Thank you, greetings

    My teacher English is not clear so sometimes I don’t understand what he’s saying and he sometimes doesn’t understand us. 🤦🏽‍♀️ so this helped a bunch. Thanks!!
