Pisum sativum Google logo!July 19, 2011 at 22:51 MDT
Today's Google logo, in honor of the July 20 birthday of Gregor Mendel, is constructed of the pods of Pisum sativum (garden pea). Mendel's careful experiments and observations helped found the discipline we now know as Genetics. G and Y in the image indicate the wrinkly green and smooth yellow pea phenotypes Mendel observed in his cross-breeding experiments.
