Chromosomal copy number variation reveals differential levels of genomic plasticity in distinct Trypanosoma cruzi strains
(BioMed Central, 2015)
Background: Trypanosoma cruzi, the etiologic agent of Chagas disease, is currently divided into six discrete typing units (DTUs), named TcI-TcVI. CL Brener, the reference strain of the T. cruzi genome project, is a hybrid ...
Possible origin of polymorphism for chromosome number in the assassin bug Zelurus femoralis longispinis (Reduviidae: Reduviinae)
(Wiley Blackwell Publishing, Inc, 2013-10)
In this study, we analysed a population of Zelurus femoralis longispinis polymorphic for chromosomal number. The fundamental karyotype of this subspecies is 2n = 22 = 20A + XY (male), but individuals with 2n = 23 = 20A + ...
Using telomeric chromosomal aberrations to evaluate clastogen-induced genomic instability in mammalian cells
(Springer, 2020-12)
Telomeres, the specialized nucleoproteic complexes localized at the physical ends of linear eukaryotic chromosomes, play a fundamental role in maintaining chromosomal stability and integrity, being one of the leading ...
Meiosis and Chromosome Painting of Sex Chromosome Systems in Ceboidea
(Wiley-liss, div John Wiley & Sons Inc., 2001-02)
The identity of the chromosomes involved in the multiple sex system of Alouatta caraya (Aca) and the possible distribution of this system among other Ceboidea were investigated by chromosome painting of mitotic cells from ...
Sex chromosome evolution in cotton stainers of the genus dysdercus (Heteroptera: Pyrrhocoridae)
(Karger, 2009-12)
The neo-X and neo-Y sex chromosomes of Dysdercus albofasciatus represent a unique model for the study of early stages of sex chromosome evolution since they retained the ability to pair and recombine, in contrast to sex ...
Kinetic activity of the sex chromosomes of Mormidea paupercula (Pentatomidae, Heteroptera)
(Czech Academy of Sciences, 2010-07)
InMormidea paupercula (n = 6 + XY in males), the presence of a CMA3-bright band in the telomeric regions on both sexchromosomes allowed the analysis of the kinetic activity of the sex univalents and XY pseudobivalent at ...
Structural chromosome instability: Types, origins, consequences, and therapeutic opportunities
(Molecular Diversity Preservation International, 2021-06)
Chromosomal instability (CIN) refers to an increased rate of acquisition of numerical and structural changes in chromosomes and is considered an enabling characteristic of tumors. Given its role as a facilitator of genomic ...

The Chromosomes of Birds during Meiosis
(Karger, 2017-02)
The cytological analysis of meiotic chromosomes is an exceptional tool to approach complex processes such as synapsis and recombination during the division. Chromosome studies of meiosis have been especially valuable in ...
