Resequencing of Korean long-tailed chicken
All sequenced samples were prepared according to the protocols of TruSeq DNA Nano Library Prep Kit (Illumina, San Diego, USA). Briefly, genomic DNA was fragmented using adaptive focused acoustic technology (AFA; Covaris) and end-repaired. These DNA fragments were A-tailed and went through ligation of the TruSeq indexing adapters. The products were PCR-amplified and qualified using the Agilent Technologies 4200 TapeStation (Agilent technologies). Finally, using the HiSeq-2500 platform (Illumina, San Diego, USA), the paired-end (2150 bp) sequencing was performed.
