SELECTION OF POTENTIAL YY MALES OF NILE TILAPIA Oreochromis niloticus (LINNAEUS, 1758) AND EVALUATION OF THE PERCENTAGE OF MALES OBTAINED

Successful development of YY technology depends not only in the identification of YY males (YYM), but also on the evaluation of the percentage of males obtained from them. The progeny of selected potential YYM was evaluated individually in order to determine its genetic status. In total, 12 potentia...

description Successful development of YY technology depends not only in the identification of YY males (YYM), but also on the evaluation of the percentage of males obtained from them. The progeny of selected potential YYM was evaluated individually in order to determine its genetic status. In total, 12 potential YYM and 12 normal females (XX) were selected. Potential YYM were selected taking into account external color, shape of the genital papillae and size. After individual crossing, a confirmed YYM was crossed consecutively with three XX females and three XY females to further assess the variation in the percentage of males obtained. A significant deviation from the 1:1 sex ratio expected for normal males (XY) was observed for ten of the twelve potential YYM that were evaluated, confirming YY status. Variation ranking between 88 to 93% in the percentage of males was observed in crosses between YYM and XX females. Finally, failure to obtain only 100% males was observed in crosses between YYM and XY females. This variation could be the result of the interaction of minor genetic parental factors or the water temperature during fry period. External parameter used for selection of potential YYM need to be optimized in further work.

La progenie de potenciales YYM seleccionados se evaluó individualmente para determinar el porcentaje de machos obtenido. En total, se seleccionaron 12 potenciales YYM y 12 hembras normales (XX). Los potenciales MYY fueron seleccionados considerando su coloración externa, forma de la papila genital y tamaño. Después de terminadas las cruzas individuales, un YYM confirmado fue cruzado consecutivamente con tres hembras XX y tres hembras XY para determinar la variación en el porcentaje de machos. Se observó una desviación significativa de la proporción de sexos 1:1 esperada para machos normales en diez de los doce potenciales YYM evaluados, confirmando su estatus YY. Se observó una variación en el porcentaje de machos de 88 a 93% en cruzas entre YYM y hembras XX. Finalmente, no fue posible obtener 100% de machos en las cruzas entre YYM y hembras XY. Esto probablemente fue resultado de la interacción de factores genéticos parentales menores o la temperatura del agua durante el periodo de alevín. Los parámetros externos utilizados para seleccionar potenciales YYM necesitan ser optimizados en trabajos futuros.Universidad Autónoma de YucatanPRODEP y CONACyT2019-03-26info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://www.revista.ccba.uady.mx/ojs/index.php/TSA/article/view/2541urn:ISSN:1870-0462-tsaes.v22i1.254110.56369/tsaes.2541Tropical and Subtropical Agroecosystems; Vol 22, No 1 (2019): (January - April)Tropical and Subtropical Agroecosystems; Vol 22, No 1 (2019): (January - April)1870-0462reponame:Tropical and Subtropical Agroecosystemsinstname:UNIVERSIDAD AUTÓNOMA DE YUCATÁNinstacron:UADYenghttps://www.revista.ccba.uady.mx/ojs/index.php/TSA/article/view/2541/1240https://www.revista.ccba.uady.mx/ojs/index.php/TSA/article/downloadSuppFile/2541/1128Copyright (c) 2019 Juan Pablo Alcántar Vázquez, Luis Pozos Dauzon, Daniel Calzada Ruiz, Carlos Alfonso Álvarez González, Alvaro Perez Carbajal, Rocio López Hinojosa, Carolina Antonio Estrada, Raúl Moreno de la Torrehttp://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessoai:ojs.www.revista.ccba.uady.mx:article/25412024-08-22T17:23:06Z
