Description
The transcriptome sequencing reveals the divergence of the genetic mechanism of reproductive traits in two Chinese native breeds. XH chicken was meat-type breed with low reproduction ability, with a 70~80% incidence of broodiness in population, with the duration of 15~30 d brooding, and with a production of 60~90 eggs per year. BEH chicken was layer-type breed with high reproduction ability, with a 10%~15% incidence of broodiness in population, with the duration of 7~20 d brooding, and with a production of 180 eggs per year.
