The ddRAD sequence of  Zeugodacus tau population in Chongqing,China. .
The ddRAD libraries were prepared following a protocol from Peterson, Weber, Kay, Fisher, and Hoekstra (2012) and Cao et al. (2021). In brief, genomic DNA was digested by two restriction enzymes of NlaIII and AciI (New England Biolabs, Massachusetts, USA). A pair of modified Illumina P1 (5 bp) and P2 adapters (4 bp) were ligated to the digested DNA of each individual. Fragments with a size of 420-540 bp were selected and then amplified using eight PCR amplification cycles. Libraries were sequenced on Illumina NovaSeq 6000 platform to obtain 153-bp PE reads.
