METHODOLOGICAL INFORMATION

Description of methods used for collection/generation of data:
Estonian data were collected by hunters who gathered tissue samples from harvested wolves. The reference dataset is described in the article by Harmoinen (2021).

Methods for processing the data:
DNA was extracted from tissue samples collected from harvested wolves in Estonia, and genotyped using 93 SNP markers. 
In the Estonian dataset, quality control was applied to the resulting genotype data, during which low-quality individuals were removed. 
The presented dataset contains filtered SNP analysis results. The reference dataset is described in Harmoinen (2021), 
which provides detailed information on sample collection, genotyping, and quality control procedures.

Instrument- or software-specific information needed to interpret the data:
PLINK 2.0

- Standards and calibration information, if appropriate: Standard laboratory procedures were used for DNA extraction and SNP genotyping. 
No additional instrument-specific calibration was recorded beyond routine laboratory practice.
- Environmental/experimental conditions:DNA extraction and genotyping were performed in a molecular genetics laboratory under controlled conditions.
- Describe any quality-assurance procedures performed on the data:Low-quality SNP results were excluded from further analyses, and they are not included in the dataset presented here.
- People involved with sample collection, processing, analysis and/or submission:Kirke Raidmets, Jenni Harmoinen, Mia Valtonen, Egle Tammeleht, Kristiina Prants, Inga
Jõgisalu, Maris Hindrikson
