Genomic analyses identify distinct patterns of selection in game fowl and Nami chicken.

ABSTRACT: The Xishuangbanna game fowl (GF) and Shangri-La Nami chicken (NF) represent two distinct chicken populations shaped by contrasting selection pressures. However, the genomic basis of their divergent phenotypic and physiological traits remains poorly understood. This study employed a comprehensive genomic approach to decipher their genetic adaptations, including de novo chromosome-level genome assembly for NF, whole-genome resequencing of 40 NFs, and comparative analyses against wild chicken (Gallus gallus) populations alongside our previously published GF genomic data. Our analyses revealed distinct genetic architectures between the two breeds. We identified 75 GF-specific and 76 NF-specific positively selected genes, with only six shared between breeds, indicating largely independent evolu
