This is a worksheet which can be used as a lab, or begun as homework and then assessed in class. It consists of questions regarding the individual student's traits and an optional class analysis of the frequency of dominant and recessive traits. There are twenty simple dominance questions, including an optional one that requires special materials. The class summary sheet is also optional; it is a single page and can simply be omitted if it's not used. Four questions on incomplete dominance traits and two practice or review questions that compare the simple and incomplete dominance inheritance patterns.
