Chromosomal microstructure diversity in three Astyanax (Characiformes, Characidae) species: comparative analysis of the chromosomal locations of the 18S and 5S rDNAs.

Zebrafish - 1 Feb 2015

Abstract excerpt

The species of genus Astyanax is widely distributed in freshwater neotropical zones. Astyanax is considered to be taxonomically confused, similar to other genera placed incertae sedis in Characidae. The cytogenetics of this genus is well characterized; species vary widely in diploid number, from 2n=36 chromosomes in Astyanax schubarti to 2n=50 for most species studied. The size, number, and position of different...
