Our analyzes revealed that females of pelvic-fin brooders have longer pelvic fins and a deeper abdominal concavity, and that they can carry eggs for longer than non-brooding species. QTL analyses revealed that pelvic-fin brooding is controlled by multiple and unliked loci. Genome wide comparative analyses detected no signatures of admixture between the two lineages of pelvic-fin brooders.
A previously unknown species of pelvic-fin brooder Oryzias was discover from central Sulawesi. Phylogenetic analyses reveled that the new species belongs to the same clades as other pelvic fin brooders in genus Oryzias.
A pure strain of O. eversi was rear. All F1 individuals were ddRAD sequenced. A single SNP was found to be perfectly associated, heterozygote for all males and homozygotes for all females.
