Using Dermatoglyphics from Down Syndrome and Class Populations to Study the Genetics of a complex trait

 

Tested Studies in Laboratory Teaching, 1990, Volume 11

Abstract

Dermatoglyphics is the study of epidermal ridges on the hands and feet. Ridge patterns and counts develop prenatally, are inherited, and show quantitative variation. This exercise introduces the preparation and interpretation of finger and palm prints for quantitative analysis. The techniques are simple, inexpensive, and can be adapted as an exercise on genetics for beginning or advanced students. Palm prints from individuals with Down Syndrome serve as a population sample to statistically test for differences with the class population and also create an opportunity to discuss the cause and effects of Down Syndrome.
