Someone: "There is no way you can discover the fundamental laws of genetics using pea plants."
Gregor Mendel: *smugly holds up Punnett squares and pea plant data*
That's literally how the entire field of genetics started! Mendel was just a monk growing peas in his garden, meticulously counting purple and white flowers while everyone else was like "who cares?" Fast forward to him becoming the father of modern genetics with those humble little legumes. Talk about a scientific flex! His Punnett squares are basically the "I told you so" of 19th century biology.
