Nettie Stevens

Nettie Maria Stevens is an American geneticist who discovered the sex chromosomes. In 1905, shortly after rediscovering Mendel's paper on genetics in 1900, she observed that the male powderworm produced two types of sperm, one with a large chromosome and the other with a chromosome. small. When large chromosomes fertilize eggs, they produce females, and when sperm with a small chromosome fertilize an egg, they produce a male. The pair of sex chromosomes she later studied were called the X and Y chromosomes
