Geese are key domesticated waterfowl in Asia, where annual egg number and laying duration influence economic value. To investigate the genomic basis of laying seasonality, we generated whole-genome resequencing data for 314 geese from six Chinese breeds and focused on three with contrasting reproductive schedules: low-latitude Ding'an geese, which have a prolonged laying period with moderate annual egg yield, and...
