| Abstract: | Fifty-five specimens of Steindachneridion melanodermatum were analyzed using molecular and conventional cytogenetic tools. Two polymorphisms were found: one involving the length of nucleolar organizer regions and another involving two submetacentric chromosomes previously identified as sex chromosomes. The polymorphism was confirmed by homogeneity between male and female karyotypes. Nucleotide sequencing and physical chromosome mapping were also used to identify and characterize one class of repetitive DNA, named SmAluI-Rex3. Based on the results and literature the present study offers an update of the occurrence of sex chromosome system in this species. © 2011 Springer Science+Business Media B.V. |
