The program of sex chromosome pairing in meiosis is highly conserved across marsupial species: Implications for sex chromosome evolution
(GENETICS, 2005-06)
Marsupials present a series of genetic and chromosomal features that are highly conserved in very distant species. One of these features is the absence of a homologous region between X and Y chromosomes. According to this ...
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 ...
Hexavalents in spermatocytes of Robertsonian heterozygotes between Mus m. domesticus 2n-26 from the Vulcano and Lipari Islands (Aeolian Archipelago, Italy)
(PAGEPress Publications, 2018)
The size and shape of the chromosomes, as well as the chromosomal domains that compose them, are determinants in the distribution and interaction between the bivalents within the nucleus of spermatocytes in prophase I of ...
Patterns of Y-chromosome variation in South Amerindians

Characterization of sex chromosomes in rainbow trout and coho salmon using fluorescence in situ hybridization (FISH)
(2001)
With the aim of characterizing the sex chromosomes of rainbow trout (Oncorhynchus mykiss) and to identify the sex chromosomes of coho salmon (O. kisutch), we used molecular markers OmyP9, 5S rDNA, and a growth hormone gene ...
Chromosome specific markers reveal conserved linkage groups in spite of extensive chromosomal size variation in Trypanosoma cruzi
(1995)
The karyotypes of three cloned stocks, CL Brener (CL), CA I/72 (CA) and Sylvio X10/7 (X10), of Trypanosoma cruzi were studied by pulsed-field gel electrophoresis followed by ethidium bromide staining and hybridization with ...
Independent Origins of New Sex-Linked Chromosomes in the melanica and robusta Species Groups of Drosophila
(2008-01)
Background: Recent translocations of autosomal regions to the sex chromosomes represent
important systems for identifying the evolutionary forces affecting convergent patterns of sexchromosome
heteromorphism. Additions ...
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 ...

Absence of Y chromosome microdeletions in patients with cryptorchidism and hypospadias
(Freund Publishing House Ltd, 2004)
Microdeletions of the Y chromosome have been observed in some patients with cryptorchidism and severe defects of spermatogenesis. We investigated whether microdeletions of the Y chromosome may be present in patients with ...
