The Y-chromosomal STRs DYS481, DYS570, DYS576 and DYS643

Area of Science:

• Forensic genetics
• Population genetics
• Human population studies

Background:

• Y-STRs are crucial for forensic identification and population genetics.
• Previous studies have established minimal and extended Y-STR haplotypes.
• Understanding Y-STR variation in specific populations is essential for accurate forensic analysis.

Purpose of the Study:

• To investigate the Y-STRs DYS481, DYS570, DYS576, and DYS643 in a West Saxon population sample.
• To determine allele frequencies and genetic diversity of these markers.
• To assess the forensic potential of these Y-STRs by comparing their discrimination capacity with other populations.

Main Methods:

• Analysis of four Y-STR loci (DYS481, DYS570, DYS576, DYS643) in a West Saxon population.
• Allele typing based on sequencing and established nomenclature.
• Calculation of allele frequencies, gene diversities, and haplotype diversity.
• Comparison of genetic data with published population samples.

Main Results:

• Observed allele frequencies for DYS481, DYS570, DYS576, and DYS643 are reported.
• Gene diversity and haplotype diversity values were calculated for the studied markers.
• The four Y-STR markers demonstrated significant discrimination capacities.

Conclusions:

• The investigated Y-STR markers (DYS481, DYS570, DYS576, DYS643) possess high discriminatory power.
• This data contributes valuable population-specific genetic information for forensic investigations.
• The findings support the utility of these Y-STRs in forensic science and population genetic studies.
