摘要:... Wood white butterflies of the genus Leptidea are excellent models to study the role of chromosome rearrangements in speciation because they show karyotype variability not only among but also within species. In this work, we investigated genome architecture of three cryptic ...

摘要:...), Hematology Section, University of Bari, Bari, Italy Abstract: In 2008, the concept of the monosomal karyotype (MK) in adult acute myeloid leukemia (AML) patients was introduced, defined by the presence of a chromosomal aberration pattern characterized by the presence o...

摘要:... Among them, the genus Tityus (Scorpiones, Buthidae) has a labile karyotype that shows complex multivalent associations during male meiosis. Thus, taking advantage of the excellent model provided by the Buthidae scorpions, here we analyzed the chromosomal distribution of sever...

摘要:... 45X/45XY karyotype is most frequent in such cases with predominance of 45X cells in both peripheral lymphocytes and gonads. We present a rare case of a left undescended testis, normally descended right testis, with penoscrotal hypospadias, who had a normal karyotype and whose...

摘要:... We suggest an important role for pericentric inversions, tandem and centric fusions in nemacheilid karyotype differentiation. Short repetitive sequences, genetic drift, founder effect, as well as the involvement of transposable elements in the dispersion of ribosomal DNA s...

摘要:... The clinical examinations such as sex hormone test and B ultrasound were performed and the genetic characterization of patients were evaluated by karyotype analysis, polymerase chain reaction and DNA sequencing. The six cases with 46, XY karyotype were diagnosed with CAIS...

摘要:... The “Robertsonian-translocation hypothesis” suggests a regular fusion of each ancestral acro- or telocentric chromosome to just one other by centromere fusions, thus halving the karyotype. An alternative “genome-stirring hypothesis” posits haphazard and repeated fusi...

摘要:In this paper, we present for the first time data on karyotype analysis ofleeches of the genus Baicalobdella (Piscicolidae) parasitizing Lake Baikalendemic cottoid fishes. Both mitotic and meiotic chromosomes are described.Leech testisacs were processed by a “shaking-blot...

摘要:Neo-XY sex chromosome determination is a rare event in short horned grasshoppers, but it appears with unusual frequency in the Pamphagidae family. The neo-Y chromosomes found in several species appear to have undergone heterochromatinization and degradation, but this subject need...
