Datasets are the following: AllSites.vcf Variant Call Format file with all filtered 7,745,655 SNPs used in the GWAS for the present study. AllSNPS_BFs.txt Post GWAS information with SNP contig, position, polymorphism and corresponding Bayes factor score for each of the 7,745,655 SNPs used in the present study. BP_allpops.ann2.vcf Variant Call Format file with 25,854 candidate SNPs chosen for the decisively strong Bayes factor score of >50. Additionally, SNPEff annotations and variant impact predition information are included on the tailing end of each line of SNP data. BPandFET_blastp_annotationSummary2Feb.xlsx DAVID gene ontology information including homologs associated with H. rubra transcripts. Each sheet represents the variant impact and species of origin for annotated genes.
