Illumina seq of pool of 15 Braula coeca flies
Genomic DNA was extracted from 15 unsexed individuals conserved in alcohol, using the Nucleobond AXG20 kit and buffer set IV from Macherey-Nagel (ref. 740544 and 740604, https://www.mn-net.com, Dren, Germany). Illumina paired-end sequencing was performed by Novogene Company Limited (https://en.novogene.com, Cambridge, UK) on the same DNA sample.
