Description Joe Hin Tjio (1919-2001) at his office at the National Institutes of Health. Modern cytogenetics, the branch of genetics studying the relationship between heredity, variation and the structure of chromosomes, began in 1956 when Dr. Tjio discovered that the human body carried 46 chromosomes instead of 48. He came to the United States and worked at NIAMD where he extended his chromosome work, studying leukaemia and mental retardation.
