I use this worksheet after the students have a firm grasp on punnett squares. It explains the results that Gregor Mendel got while working with the pea plants on the monastery. This activity supports California State 7th Grade Science Standard 2D - Students know plant and animal cells contain many thousands of different genes and typically have two copies of every gene. The two copies (or alleles) of the gene may or may not be identical, and one may be dominant in determining the phenotype while the other is recessive.
