Walter Sutton
Walter Sutton was an American geneticist who, in the early 20th century, helped establish the chromosome theory of inheritance. Through his studies of grasshopper cells, he observed that chromosomes come in pairs and behave similarly during cell division, suggesting they carry genetic information. This discovery provided key evidence that genes are located on chromosomes, fundamentally advancing our understanding of heredity. Sutton's work bridged genetics and cytology, shaping modern genetics and explaining how traits are passed from parents to offspring.
