References Abstract Nettie Stevens has been recognised recently for her careful research postulating that the chromosomes are involved in the inheritance of a specific character, sex. The background of her achievement is discussed, including the behaviour of the chromosomes in cell division, the results of experimental breeding, and the possibility that the two are related.
