Mendalism vs Mendelism

The General Sterling Price teaches us the difference between Mendalism and Mendelism:

Mendalism is simply "The unauthorized repair of damaged art"

Mendelism, on the other hand, although often misspelled as "mendalism", is "the theory of genetic inheritance based on Mendel's laws"
