This paper discusses the individuation of characters for the use asunits by geneticists at the beginning of the 20th century. Thediscussion involves the Presence and Absence Hypothesis as a case study. It issuggested that the gap between conceptual consideration and etiological factorsof individuating of characters is being handled by way of mutual adjustment.Confrontation of a suggested morphological unit character with experimentresults molded the final boundaries of it.
