High MHC gene copy number maintains diversity despite homozygosity in a Critically Endangered single-island endemic bird, but no evidence of MHC-based mate choice

Raw sequence data from two amplicon libraries of MHC class I exon 3 of Raso Lark Alauda razae, sequenced on an Illumina Miseq. The two different libraries (two different Illumina runs) are collected in separat tar archive (.tar). Within each of those are individual sequence reads as gzipped fastq files (.fastq.gz). Each sample has two files, one for read 1 (R1) and one for read 2 (R2), with file names structured as follows. Delimited by underscore (_) are:

sample name as referred to in the data and paper (“RingNo” in the Supporting data table);

formal ID (also referred to in data table, often corresponding to full ring number);

Illumina sample number (i.e. based on the order that samples are listed in the sample sheet);

Illumina lane number (static as L001, as Miseq instruments have a single lane on their flow cells);

read number (R1 [forward] or R2 [reverse]);

static identifier from Illumina (001).

Thus, the file 83304_TJ83304_S163_L001_R2_001.fastq.gz is the reverse (read 2) MHC class I exon 3 sequence of individual 83304 (ring number TJ83304).
