To narrow down the genomic regions guilty for the 2 traits, 136 extra fish of proven phenotypes, from China, Thailand, Malaysia, Singapore, and Indonesia were genotyped using both RAD sequencing and SNP/indel markers developed from resequencing data, as described above. Genotypes were used to determine recombinants in the foremost loci deciding on double tail and albino. For dorsal fin recognizing, parents, DtY2female and F0B1male showed noticed and nonspotted dorsal fin, respectively, while F1 folks, RM2female and RM2male showed spotted and nonspotted dorsal fin, respectively. Due to a phenotypic interplay of iridescent pigmentation styles and the albino condition, which also segregated in the F2 mapping crosses, only 156 people from the RM2 family can be phenotyped. This trait offered a segregation ratio of 1:1 for noticed versus nonspotted dorsal fin. We carried out both quantitative trait loci QTL mapping and mixed linear modeling for this trait using these 156 phenotyped fish.
