Alfred Sturtevant

Alfred Sturtevant was an American geneticist known for his pioneering work in the field of genetics during the early 20th century. He is best recognized for creating the first genetic map of a chromosome, which helped to identify the locations of genes. Sturtevant used fruit flies (Drosophila) in his experiments to demonstrate how traits are inherited and how genes are spaced on chromosomes. His research laid the groundwork for modern genetics, significantly contributing to our understanding of heredity and the structure of genetic material. Sturtevant's innovations have had a lasting impact on biology and medicine.
