Summary
This study analyzed Y-chromosome short tandem repeat (STR) loci in 104 Romanian males. High genetic diversity was observed, with 92 unique haplotypes out of 97 total, indicating significant Y-STR variation in this population.
Area of Science:
- Forensic Genetics
- Population Genetics
- Human Genetics
Background:
- Short tandem repeats (STRs) on the Y-chromosome are valuable genetic markers for male lineage studies.
- Understanding Y-STR variation within populations is crucial for forensic applications and anthropological research.
- Previous Y-STR data for the Romanian population is limited.
Purpose of the Study:
- To characterize the genetic diversity of seven Y-STR loci in a Romanian male population.
- To establish a Y-STR haplotype reference database for the Romanian population.
- To assess the forensic efficiency of these Y-STR markers in Romania.
Main Methods:
- DNA samples from 104 unrelated Romanian males were analyzed.
- Seven Y-STR loci (DYS19, DYS385, DYS389 I/II, DYS390, DYS391, DYS392, DYS393) were amplified using multiplex PCR.
- Amplified products were analyzed by capillary electrophoresis.
Main Results:
- A total of 97 distinct Y-STR haplotypes were identified.
- Ninety-two of the observed haplotypes were unique to individuals.
- The overall haplotype diversity was calculated to be 0.989, indicating high genetic variability.
Conclusions:
- The analyzed Y-STR loci exhibit high discriminatory power in the Romanian male population.
- The findings contribute valuable data for forensic investigations and population genetics studies in Romania.
- The observed high haplotype diversity suggests extensive Y-chromosome variation within this population.
