Genome-wide SNPs in the spiny lobster Panulirus homarus reveal a hybrid origin for its subspecies

BMC Genomics

Table 3 Potential hybrid individuals and their estimated genetic background. Only a few representative hybrids from NWIO are listed, as most NWIO samples are admixed

^a Sampling codes: Za, Sa – South Africa; Cc, Cr, L, Cd, Om (Oman) – NWIO locations
^b Posterior probabilities of belonging to different category genetic backgrounds: P1 – pure pop 1; P2 – pure pop. 2; F1 – F1 hybrid; F2 – F2 hybrid; FxPx: backcross of Fx hybrid to population x
^c Assignment probabilities to different genetic clusters, determined by admixture LEA analysis
^d mtDNA clade
^e DArTseq genotyping for this sample was not successful
^f PhOm02 and PhCd10 are representatives pure NWIO-specific lineage
