Low-pass whole genome sequence of indigenous Tigray chicken

This dataset contains low-pass whole genome sequencing (lpWGS) data generated by Gencove for indigenous chickens sampled across diverse agroecological zones in the Tigray region of northern Ethiopia. The study aims to investigate genetic diversity, local adaptation, and environment-genotype relationships by integrating genomic data with detailed environmental information. DNA was extracted from mature and healthy chickens representing multiple ecotypes, and sequencing was performed using the Gencove low-pass whole genome sequencing platform SkimSeek (Neogene Europe Limited). Sequencing coverage ranged from 0.2x to 1.99x, and genotype imputation was conducted using the Gencove pipeline with a high-coverage African chicken reference panel. The raw reads deposited here support downstream analyses including genotype imputation, variant discovery, population structure, and genotype-environment association studies.
