Report of the variability of the sequence of the kitlg a receptor gene associated with pigmentation in Mikrogeophagus Ramirezi‎ (Myers & Harry, 1948) (Perciformes: Cichlidae)

Abstract

Dwarf cichlids cycles are very popular in cooking in Peru. However, the difference in color of pigmentation due to its wide range of varieties of different species for future genetic improvement by molecular selection limits its commercial development and the genetic basis of the variation of pigmentation can also be ignored. In this study, we followed the genus Kitlg a des varieties Velo and German Blue of the cyclid Mikrogeophagus ramirezi (Myers & Harry, 1948). A following consensus was generated of 176 pb which was used as a comparative reference with other ornamental fish species reported where the similarity ratio (%) was: 25 with the Cebra fish (Danio rerio Hamilton, 1822), 11.9 with the Goldfish (Carassius auratus, (Linnaeus, 1758), 11.4 with the Espada (Xiphophorus helleri Heckel, 1848) and the Platy (Xiphophorus maculatus Günther, 1866) and 15.9 with the Guppy (Poecilia reticulata Peters, 1860). These first results at the molecular level will facilitate a better understanding of the mechanisms of color pigmentation differentiation in the Mikrogeophagus genus.
