A new derived and highly polymorphic chromosomal race of Liolaemus monticola (Iguanidae) from the 'Norte Chico' of Chile
(1998)
A multiple Robertsonian fission chromosomal race of the Liolaemus monticola complex in Chile is described and is shown to be the most derived and the most complex among the Liolaemus examined thus far. The 29 karyotyped ...
Robertsonian chromosomes and the nuclear architecture of mouse meiotic prophase spermatocytes
(BioMed Central, 2014)
Background: The nuclear architecture of meiotic prophase spermatocytes is based on higher-order patterns of
spatial associations among chromosomal domains from different bivalents. The meiotic nuclear architecture depends
on ...

Further Evidence of Chromosome Abnormalities in Normal and Haploid Gynogenetic Progenies of Rainbow Trout, Oncorhynchus mykiss
(1996)
Gynogenetic haploid progenies of rainbow trout, produced using UV light for sperm
inactivation, were studied in comparison with normal progenies. In a total of 437 normal embryos,
3.5% of them showed chromosome abnormalities: ...
Evolution of trans-andean endemic fishes of the genus Cheirodon (Teleostei: Characidae) are associated with chromosomal rearrangements
(Sociedad de Biología de Chile, 2018-07-03)
Background: Among Neotropical fishes, the family Characidae is highly diverse and speciose and its taxonomy is not completely resolved. In Chile, the family is represented by five species, all within the genus Cheirodon, ...
Chromosome numbers in insects of Argentina I. Cytogenetic characterization of 15 species with economic importance.
(Universidad del ValleColombia, 2020-07-09)
In the present study, the somatic and gametic chromosome numbers in fifteen species of insects from Argentina are reported. Said species are characterized for their economic importance as pest of crops or as agricultural ...
chromPlot: visualization of genomic data in chromosomal context
(Oxford Univ Press, 2016)
Visualizing genomic data in chromosomal context can help detecting errors in data processing and may suggest new hypotheses to be tested. Here, we report a new tool for displaying large and diverse genomic data along ...
The frequency of heterologous synapsis increases with aging in Robertsonian heterozygous male mice
(Springer, 2012-02)
The house mouse is characterised by highly variable chromosome number due to the presence of Robertsonian (Rb) chromosomes. During meiosis in Rb heterozygotes, intricated chromosomal figures are produced, and many unsynapsed ...
The robertsonian phenomenon in the house mouse: mutation, meiosis and speciation
(Springer Science and Business Media Deutschland GmbH, 2014)
© 2014, Springer-Verlag Berlin Heidelberg. Many different chromosomal races with reduced chromosome number due to the presence of Robertsonian fusion metacentrics have been described in western Europe and northern Africa, ...
Partial-AZFc deletions in Chilean men with primary spermatogenic impairment: gene dosage and Y-chromosome haplogroups
(Springer, 2020)
Purpose To investigate the association of partial-AZFc deletions in Chilean men with primary spermatogenic failure and their testicular histopathological phenotypes, analyzing the contribution ofDAZdosage,CDY1copies, and ...
