    For the analysis of genetic mixture profiles, the objective of this study was to apply interpretation criteria of the analysis of genetic mixture profiles, in forensic evidence of sexual violence of Peruvian women, in the Molecular and Genetic Biology Unit; 2019-2020. The research design is non-experimental, applied, cross-sectional and descriptive. 141 forensic evidence from 36 criminalistics cases were analyzed where it was possible to determine that the genetic profiles met the criteria for general interpretation of mixed profiles, for which 98% exceeded the analytical threshold (≥ 50 RFU), 82% exceeded the threshold stochastic (≥ 150-200 RFU), 60% exceeded the stutter threshold (≥ 10-15% RFU), 92% presented heterozygote imbalance (< 0.6), the proportion of contributors 0.1-1 was distinguishable in 62 %, the extrabands recognizable in 60% were the stutters, the presence of genetic artifacts was in 44% and the stochastic, degraded and/or inhibited profiles are related to the types of mixture profiles. In the criminal cases of a single aggressor, they met the general thresholds of scientific recommendation, likewise the mixed profiles were interpretable, the conclusive cases were in 78 pieces of evidence and the inconclusive cases were in 13 pieces of evidence. In the criminal cases of multiple aggressors, the mixed profiles met the general thresholds of scientific recommendation, likewise these profiles were interpretable, the conclusive cases were 41 pieces of evidence and the inconclusive cases were 9 pieces of evidence.
