The fingerprints of 15 MZ and 15 DZ female twin pairs have been studied for methodological purposes. Zygosity has been ascertained both on account of similarity criteria (polysymptomatic method, etc.) and of concordance ones (blood groups). The data have been analyzed both qualitatively and quantitatively. The complexity of the qualitative analysis has required an apposite methodology and the use of a 1620 IBM computer.
Similarities — at the qualitative level — and concordances — at the quantitative one — appear to be significantly different respectively in MZ and DZ twin pairs.
No conclusions are drawn from the present results. The final work, based on 100 twin pairs (cf. Tab. 1.1) will possibly allow better understanding of some topics rapidly dealt with in this mainly methodological note.
