Start with “Co-Dominance” and read and do everything on the site. However while you need to fill in the tables on the site to figure things out, you do not have to answer the questions in the boxes on the site. Below you will find boxes with some of their questions, and some of my own. You will be graded on these answers.

Answer the questions as best you can. The boxes will expand as you type if you need more space. (Don't worry if it is a one word answer. The box size is standard.)
