Correlation between ring finger length and athletic ability
The hypothesis that most of the athletic girls will have a longer ring finger than index finger has been proven to be true.
The finger length ratio can be used to help identify potential athletes for training and grooming while they are still young. It has always been known that sports and athletic abilities are genetically inherited and the same genes might hold the answer to the finge- length ratio.
What would happen if the science fair project was done to compare the finger length ratio of athletes in different areas of sports?
The experiment may be repeated to compare the finger length ratio in male athletes.
Also, what about toe length? If the finger-length ratio gives us clues about a person's athletic abilities, perhaps their toes may also do so?
