siamese fighting fish spitting out foodFor dorsal fin recognizing, fogeys, DtY2female and F0B1male showed noticed and nonspotted dorsal fin, respectively, while F1 fogeys, RM2female and RM2male showed noticed and nonspotted dorsal fin, respectively. Due to a phenotypic interplay of iridescent pigmentation styles and the albino situation, which also segregated in the F2 mapping crosses, only 156 americans from the RM2 family can be phenotyped. This trait supplied a segregation ratio of 1:1 for noticed versus nonspotted dorsal fin. We performed both quantitative trait loci QTL mapping and mixed linear modeling for this trait using these 156 phenotyped fish. As the outcomes in QTL mapping peak LOD score and PVE were 282. 79% and 100%, respectively and mixed linear modeling were constant, we only latest the outcomes of the mixed linear modeling.
