In 1899-1907 he worked at Harvard University in 1907-1914 served as Professor of Botany and Genetics, Connecticut Agricultural College (now University of Connecticut).

The main work Blakeslee devoted to the study of mutants. In 1904, Blakeslee discovered the phenomenon in fungi heterothallic (dioecious, expressed in the physiological and genetic differences between the sexes without morphological differences in male and female). For the first time applied the method of the impact of colchicine on mitosis in plant cell to obtain polyploids (1937). To study the genetic balance in the chromosome mutants using a new object - a narcotic plant. Studying the process of mutations on this plant, showed that many mutations are to add an extra chromosome in one pair of normal chromosomes. Blakeslee died in Northampton (pc.
