| "description": "This dataset contains genotypes from chromosome chr22 for a subset of samples from the 1000 Genomes Project and HGDP. For this specific dataset, 50k SNPs at random positions were selected from the original sequences and missing values where introduced with a probability of 0%. The task is to predict the specific subpopulation of each sample based on the genotypes.", |
| "source": "Chromosome data was dowloaded from GnomAD v3.1.2 - 1KG + HGDP callset: https://gnomad.broadinstitute.org/downloads#v3-hgdp-1kg. Fine-grained subpopulation labels (e.g., GBR, CHB, YRI) were obtained from the harmonized gnomAD v3.1 sample metadata.", |
