dc.description | Previous studies on the mitotic chromosomes of three populations of Isognomon alatus from different localities along the Gulf of Mexico revealed chromosome polymorphism and differences in the diploid number. In this study, an analysis of the meiotic behaviour of I. alatus from Veracruz, Mexico, has been carried out in order to obtain complementary information to the knowledge of the cytogenetics of this species. Our results indicate complementary homologous chromosomes during pachytene and 14 symmetric chiasmated bivalents during diakinesis. No sexual chromosomes were identified. There was no evidence of chromosome polymorphism nor intrapopulation alterations of the diploid number. | en-US |
dc.description | Estudios previos de los cromosomas mitóticos de tres poblaciones de Isognomon alatus en localidades distintas en el golfo de México indicaron la presencia de polimorfismo y diferencias en el número diploide. En este estudio se realizó un análisis del comportamiento meiótico de los organismos correspondientes a la población de Veracruz, México, con el fin de obtener información adicional que permita conocer mejor la citogenética de esta especie. Los resultados obtenidos indican que los cromosomas en paquinema y diacinesis reflejan complementariedad y se presentan agrupados en 14 bivalentes simétricos sin indicios de cromosomas sexuales. No se encontraron evidencias de polimorfismo cromosómico ni alteraciones al número diploide a nivel intrapoblacional. | es-ES |
