Cytogenetic survey of species of two distinct genera of Iberian nases (Cyprinidae, Leuciscinae) that hybridize extensively in nature. I. Evidence of a similar and conserved chromosome pattern with some few species-specific markers at macro-structural level.

Abstract excerpt

Pseudochondrostoma duriense and Pseudochondrostoma polylepis hybridize extensively with Achondrostoma oligolepis in natural populations. In this first survey, karyotypes were comparatively analyzed by C-, AgNOR- and CMA(3)-banding procedures in pure (non-introgressed) fish specimens. Leuciscinae pattern was evidenced in the three species: metacentrics and submetacentrics dominance, a big subtelo/acrocentric...
