DETERMINATION OF THE TYPE OF INHERITANCE OF THE “LYRA”, “VELIFEROUS” AND “SIMPLE” FORMS OF THE CAUDAL AND DORSAL FINS IN SWORDFISH (XIPHOPHORUS HELLERI, HENCKLE, 1848)

However, despite the diversity of known traits, classical genetic studies to determine the hereditary shape of the caudal and dorsal fins are few. Th e present investigation employing directed crosses was able to identify the dominant form of the caudal fi n of “Lira form” and the dorsal fi n of “Veliferous form”. Both traits were dominant over the recessive trait "Simple form" in both the caudal and dorsal fi ns (F1). Likewise, through directed crosses of the two traits, it was statistically determined by the Chi-Square test that the forms of inheritance of both traits were segregated in the F2 in the Mendelian ratio 9: 3: 3: 1. Th is would allow the genetic improvement of the shape of the fi ns in the Swordfi sh and obtain improved lines with greater commercial value for the ornamental aquaculture.Es conocida la importancia del pez Espada (Xiphophorus helleri Henckle, 1848) para la acuicultura ornamental actual. Sin embargo, a pesar de la diversidad de rasgos conocidos los estudios de genética clásica para determinar la forma hereditaria de las aletas caudales y dorsales son pocos. La presente investigación mediante cruzamientos dirigidos logró identifi car la forma de dominancia de la aleta caudal de “forma Lira” y de la aleta dorsal de “forma Velífera”. Siendo ambos rasgos dominantes sobre el rasgo recesivo “forma Simple” tanto en la aleta caudal como en la aleta dorsal (F1). Asimismo, mediante cruces dirigidos de los dos rasgos se determinó estadísticamente por la prueba de Chi Cuadrado que las formas de herencia de ambos rasgos se segregaron en la F2 en la proporción mendeliana 9:3:3:1. Esto permitiría realizar la mejora genética de la forma de las aletas en el pez Espada y obtenerse líneas mejoradas con mayor valor comercial para el acuicultor ornamental.Facultad de Ciencias Biológicas, Universidad Ricardo Palma2020-10-12info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdftext/htmlhttp://revistas.urp.edu.pe/index.php/Biotempo/article/view/332410.31381/biotempo.v17i2.3324Biotempo; Vol. 17 Núm. 2 (2020): Biotempo; 281-2862519-56971992-215910.31381/biotempo.v17i2reponame:Revistas - Universidad Ricardo Palmainstname:Universidad Ricardo Palmainstacron:URPspahttp://revistas.urp.edu.pe/index.php/Biotempo/article/view/3324/4088http://revistas.urp.edu.pe/index.php/Biotempo/article/view/3324/8132Derechos de autor 2020 Biotempoinfo:eu-repo/semantics/openAccessoai:oai.revistas.urp.edu.pe:article/33242023-02-28T07:13:37Z |
