“…The three studied species have wide geographic distributions and the data shown here represent the most austral cytogenetic reports consistent with the previously published karyotypes (Brum-Zorrilla and Langguth, 1980;Hatanaka and Galetti Jr, 1999;Hatanaka et al, 1998;Nash et al, 2001;Pieńkowska-Schelling et al, 2008;Wayne et al, 1987). The 2n= 74, NF= 76 chromosome complement is highly conserved in most endemic Neotropical species with the exception of C. brachyurus that presents 2n= 76, and C. thous showing a large proportion of bi-armed autosomes.…”

“…Species described from the family Canidae have 2n between 34 and 78. Most chromosomes are mono-armed in species with higher diploid chromosome numbers, while in species with lower 2n, they are bi-armed (Hatanaka and Galetti 1999).…”

SummaryThis study conducted karyological analysis and detection of nucleolar organizer regions (NORs) in the Asiatic jackal (Canis aureus Linnaeus, 1758) from Khao Suan Kwang Zoo, Khon Kaen Province, Thailand. Blood samples were taken from two male and two female jackals. After standard whole blood lymphocytes had been cultured at 37 C for 72 h in the presence of colchicine, metaphase spreads were performed on microscopic slides and air-dried. Giemsa s staining, GTGbanding, high-resolution banding and Ag-NOR banding techniques were used to stain chromosomes. The results showed that the diploid chromosome number of C. aureus was 2n=78 and the fundamental numbers (NF) of both sexes were 80. The types of autosomes were 18 large telocentric, 18 medium telocentric and 40 small telocentric chromosomes. The X chromosome was the largest metacentric chromosome and the Y chromosome was the smallest acrocentric chromosome. In addition, the long arm near the centromere of chromosome pair 7 and the long arm near the telomere of chromosome pairs 10 and 28 contained NORs. From the GTG-banding and high-resolution banding techniques, the numbers of bands were 205 and 269, respectively, and each chromosome pair could be clearly differentiated. The karyotype formula for C. aureus is: 2n (diploid) 78=L

In spite of a few tools, cytogenetical analyses have made important contributions to the understanding of natural populations' biodiversity. The fluency of some subjects can be limiting specially for early investigators of this area. Aiming to contribute to the understanding of karyotypic dynamics of species, and to elucidate its cytogenetics relationships as well, a dichotomyc key for the identification of sex chromosomes and chromosomal polymorphisms was developed. Profound analyses of karyotypic macrostructure can be done with this tool. However, relatively simple and routine data on the genome organization are needed.
