Notes The Work of Gregor Mendel Mendel studied 7 different pea
... Mendel studied 7 different pea plant traits. A trait is a characteristic that varies from one individual to the next, i.e. plant height. Each trait had 2 contrasting forms, i.e. tall or short. Today, scientists call the chemical factors that determine traits genes. The different forms of the gene ar ...
