Although most of fish and amphibians species do not have differentiated sex chromosomes, there is a great diversity concerning the mechanisms of chromosomal sex determination including heterogametic females or males and single or multiple systems. In most cases, a difference between the sex partners involves heterochromatic blocks and this fact is very well established in ZZ/ZW systems in…
Among the Siluriformes, Loricariidae family is widely distributed with approximately 860 species, of which the tribe Ancistrini is the largest in number of species, having 217 valid species, distributed in 29 genera. The genus Ancistrus, is one of the most diversified tribe and now has 74 nominal species, but still rather dubious taxonomy and many unidentified species. Systematic and phyl…
While most fish species do not show sex chromosomes differentiated, there is a great diversity concerning the mechanisms of chromosomal sex determination, including heterogametic females or males and single or multiple systems. In most cases, the difference between sex chromosomes involve heterochromatic blocks and this fact is well established in ZZ:ZW system, where loss or gain of heter…

Satellite DNAs (satDNAs) are non-coding sequences that are highly repeated in tandem, and are usually located in pericentromeric, centromeric and subtelomeric chromosomal regions, and being one of the most abundant components of the eukaryotic genome. These sequences are organized within species into different families, with each species having a library of satellites, whose set can be ca…
The genomes of eukaryotes are characterized by containing a large number of highly dynamic repetitive sequences, either at the chromosomal or nucleotide level, with several factors contributing to their duplication and expansion, modulating or evolving to karyotype evolution in different organisms. Among these sequences, satellite DNAs (satDNAs) are among the most dynamic repetitive eleme…
The repetitive sequences act in important processes and cellular arrangements, as, for example, in the evolutionary dynamics of the sex chromosomes and in the structuring of centromeric heterochromatin, besides providing relevant information on the speciation and phylogeny of related species. The most represented category of repetitive DNA in the genome is satellite DNA, which has been wi…
Currently, they are described to order Anura 6, 929 species that are distributed on virtually all continents, except Antarctica, with Brazil being registered to an occurrence of 1,080 species. There are now 51 species found for the genus Lithobates, Anura, Ranidae, distributed throughout the Americas, with only two occurrences in Brazil, emphasizing that one of them is exotic. Therefore, …
