Gregor Mendel was able to observe patterns of inheritance through his experiments with Pea Plants. Luckily for Mendel, Pea Plants... select all that are true

• Are easy to control pollination

• Produce large quantities of offspring

• Are poisonous and easily avoid predators

• Have traits that exist in only 2 forms

• I don't know
