Abstract excerpt

OBJECTIVES: To standardize the calculation method of the parentage index (PI) for short tandem repeat (STR) tri-allelic genotypes, thereby ensuring the accuracy and reliability of parentage tes‑ ting conclusions. METHODS: A systematic analysis of 160 real cases was conducted. A classification system was constructed based on the occurrence mechanisms and inheritance patterns of STR tri-alleles, and the PI...
