DMIT (Dermatoglyphics) Introduction of (DMIT) Dermatoglyphics Dermatoglyphics is the study of ridged skin patterns (also known as dermatoglyphs) which can be found on fingers, palms, toes and soles. These patterns are formed from the external ectoderm and usually occur during the fetal development stage, 13 to 19 weeks after fertilization. Through research, geneticists have proven that Dermatoglyphs formations are controlled by chromosomes, and the patterns are influenced by polygenetic inheritance. These genes do not exhibit dominance, and they are very resistant to acquired changes from the environment.

Using their morphologies, the patterns can be classified into two categories, namely “ridges” and “furrows”. During the seventh week of pregnancy, vertical thumb creases (thenar contours) begins to appear on the palm of the embryo. Two weeks later, remote and proximal horizontal…
