Note on the karyotype and NOR phenotype of cyprinid fish Parachondrostoma arrigonis

Popis výsledku v původním jazyce

Karyotype and cytogenetic characteristics of critically endangered Iberian endemic cyprinid fish Parachrondrostoma arrigonis (Steindachner, 1866) were investigated using sequential C-banding, Ag- and CMA3-stainings in two specimens identified on morphological criteria. The diploid chromosome number was 2n = 50 with 8 pairs of metacentrics, 14 pairs of submetacentrics to subtelocentrics and 3 pairs of subtelo-acrocentrics. The largest chromosome pair of the complement was characteristically subtelo- to acrocentric. In the single analysed male, the nucleolar organizer regions (NORs) detected by Ag- and CMA3-stainings were in the telomeres of a single, middle-sized subtelocentric chromosome pair which is a pattern common in a number of other Leuciscinae.In the single analysed female, in which we could not confirm or reject interspecific hybridization, the NOR phenotype detected by these stainings showed at least seven positive sites on various chromosomes including characteristic large s
