Problem:Context: The proposition that finger print variability between individuals might be reduced by the absence of an X-chromosome in Turner's syndrome was rejected. In the present study of 58 XO patients, aged 15-50 years, relatives of several cases, unrelated female control samples and three unrelated male samples were investigated. The higher mean value of the TRC among patients supported the hypothesis forwarded by Penrose that an added X- or Y-chromosome reduces the TRC and a missing one increasing it. The figures do not speak against the hypothesis that genes affecting the TRC are located on the X-chromosome. A summary of the major dermatoglyphic investigations in Turner's syndrome is presented.
Question: What chromosome is affected in Turner's syndrome?
Solution:
x
