Frjeda Blanchard, née Cobb (October 2, 1889 – August 29, 1977), was an American plant and animal geneticist, the first to demonstrate Mendelian inheritance in reptiles.
Frjeda Blanchard was born on October 2, 1889, in Sydney, Australia, daughter of the plant pathologist and nematologist, Nathan Cobb.
After helping her father with his nematode research later that year, Blanchard was offered a position with the University of Michigan's Matthaei Botanical Gardens by its director, Harley Harris Bartlett.
She became assistant director three years later and received her Ph.D from the university in 1920, after researching Mendelian inheritance in strains of Oenothera (evening primrose).
The couple collaborated researching garter snakes, Frank focused on life history, while Frjeda concentrated on genetics, being the first scientist to document Mendelian inheritance in reptiles.
