Sex chromosome polymorphism in a species of Belostoma (Belostomatidae, Heteroptera)

Mostrar todas las versiones(3)

A population of Belostoma sp. polymorphic for the sex chromosome determining system has been analyzed. The fundamental karyotype of the species is 2n = 16 = 14 + XY (male), and at different times individuals 2n = 17 have been encountered in a low frequency (27% and 16%, respectively). Sex chromosome...
