Utilization of cytogenetic technics in paternity investigation.
The joint analysis of several genetic markers in cases of paternity investigation renders possible a cumulative probability of 99.7% of chance of exclusion of a falsely accused father. The role of heteromorphisms of the Y chromosome size was appraised in this work, with more than one genetic marker, in 20 expertise examinations in paternity investigation, where the children were male. The results found with this method, in association with the research on erythrocytic and leucocytic antigens showed the exclusion of two falsely accused men. Cytogenetics analysis with Giemsa stain in combination with leukocyte (HLA system) and erythrocyte antigens investigation demonstrated the exclusion of two men falsely accused.
