Whole genome data of male black grouse chick
A single library was prepared for all chick samples by Biomarker Technologies (BMK) GmbH using the VAHTS Universal Plus DNA Library Prep Kit for Illumina (ND617) following the manufacturers protocol. Fragmented and end repaired DNA was size-selected using magnetic beads, followed by adapter ligation and clean-up using VAHTS DNA Clean Beads. The library was amplified using a polymerase chain reaction (PCR) and subjected to quality control. Fragment sizes were assessed using Qsep-400 and DNA concentrations were quantified using a Qubit 3.0. Whole genome (150bp paired-end) sequencing of all the chick samples was conducted on a single Illumina NovaSeq X Plus lane at the Beijing Genomics Institute (BGI). Adaptor sequences and low-quality reads (those with average quality scores below 20) were removed.
