McClintock Corn (IMAGE) Cold Spring Harbor Laboratory Caption This ear of corn was grown and analyzed by Nobel Prize-winning Cold Spring Harbor Laboratory (CSHL) geneticist Barbara McClintock decades ago. From her observations, she surmised that parts of the corn genome jumped from one location to another, generating a great deal of genetic diversity—in this case many different colors of kernels. CSHL researchers expanded on her work by sequencing the genomes of multiple corn strains, mapping even the mobile portions of the genome.
