Identification and chromosome mapping of repetitive elements in the Astyanax scabripinnis (Teleostei: Characidae) species complex
Springer Science and Business Media LLC - Tập 143 - Trang 55-62 - 2014
Most part of the eukaryotic genome is composed of repeated sequences or multiple copies of DNA, which were considered as “junk DNA”, and may be associated to the heterochromatin. In this study, three populations of Astyanax aff. scabripinnis from Brazilian rivers of Guaratinguetá and Pindamonhangaba (São Paulo) and a population from Maringá (Paraná) were analyzed concerning the localization of the......
Identification of Two Subfamilies of micropia Transposable Element in Species of the repleta Group of Drosophila
Springer Science and Business Media LLC - Tập 121 - Trang 155-164 - 2004
The occurrence, number of insertion sites and antisense RNA expression of micropia transposable element were studied in 26 species that belong to three subgroups (mercatorum, mulleri and hydei) of repleta group of Drosophila. Under high specific PCR, micropia sequences were detected in 11 species, but under less stringent condition, this retrotransposon was detected in all species. The widespread ......
Morphology of pachytene chromosomes and its bearing on the nature of polyploidy in the cytological races of Apluda mutica L.
Springer Science and Business Media LLC - Tập 44 - Trang 234-243 - 1973
Pachytene chromosomes of diploid (n=10), hexaploid (n=30) and heptaploid (n=35) races of Apluda mutica L. are similar in their diagnostic morphological features. Hexaploids and heptaploids possess the same ten basic types of chromosomes characteristic of the diploid in multiples of six and seven respectively. Quadrivalent associations involving four homologous chromosomes were observed for all ten......
Superchromosomal organization and its cytogenetic consequences in the Eukaryota

Olfaction and human kin recognition
Springer Science and Business Media LLC - Tập 104 - Trang 259-263 - 1998
Humans, like other mammals, are capable of discriminating between kin and non‐kin by olfactory cues alone. Shortly after birth, breastfed infants become familiar with, and respond preferentially to, their mother' unique odor signature. Mothers likewise recognize the characteristic scent of their newborn infant. Close biological relatives share somewhat similar odor signatures (presumably resulting......
Multiple autosomal polymorphism in populations of Akodon simulator simulator Thomas, 1916 from Tucumán, Argentina (Rodentia, Cricetidae)
Springer Science and Business Media LLC - Tập 82 - Trang 165-175 - 1990
Cytogenetic analysis was performed on twenty seven specimens of Akodon simulator simulator collected in three different localities of Tucumán Province, Argentina. Diploid number, chromosomal morphology and C and G banding patterns were studied. Eight different karyomorphs were found, with diploid numbers of 2n=38, 39, 40, 41, and 42. All individuals showed the same number of chromosomal arms (FN=4......
