1905 Discovered XY sex-determination system

Although Stevens did not have a university position, she made a career for herself by conducting research at leading marine stations and laboratories. Her record of 38 publications includes several major contributions that further the emerging concepts of chromosomal heredity. By experimenting on germ cells, Stevens interpreted her data to conclude that chromosomes have a role in sex determination during development. As a result of her research, Stevens provided critical evidence for Mendelian and chromosomal theories of inheritance. At first, her research and findings about sex determination were not appreciated or believed because of the gender bias in science. Another researcher, Edmund Wilson made similar discoveries to her around the same time but hers were much larger leaps in the world of science and were the ideas which ended up being correct.
