What did people think about traits before Mendel? Before Mendel, people believed that the traits of offspring were simply blends of their parents e.g tall + short parent = medium offspring What did Mendel discover about traits of pea plants? Tall pea plant + short pea plant = all tall offspring pea plants. From this he figured out each parent must have a unit passed directly to the offspring that determine height. We call those units genes.
