If you look at how Mendel studied his pea plant seeds, he saw that RR and Rr genotypes of seeds produced round seeds and rr produced wrinkled. This is from a phenotypical (or you can say organismal) level. However, when scientists cracked open these seeds, it was found that the Rr genotypes had only 50% of a protein, but it still looked round. RR had 100% of the protein, and rr had 0% of the protein. This is a case of Incomplete Dominance, but Mendel didn't realize it because he had no microscope to look inside the seed.
So it's important to look at both the organismal and molecular level of genes.
