The Warm and Cool Genetics houses make up the Blakeslee Range. These greenhouses are used for research projects and materials for biology classes. This area is closed to the public.

These two greenhouses were built in 1952 as state-of-the-art research greenhouses for the distinguished geneticist, Albert Francis Blakeslee. He taught graduate courses and conducted research using Datura (jimsonweed) to study the role of chromosomes in heredity. Blakeslee also developed the "gloriosa daisy," a large flowered form of Rudbeckia (black-eyed Susan), which is widely grown in gardens today.
