Nucleolar expression and chromosomal associations in Robertsonian spermatocytes of Mus musculus domesticus
(MDPI AG, 2019)
We studied and compared the nucleolar expression or nucleoli from specific bivalents in spermatocytes of the standard Mus musculus domesticus 2n=40, of Robertsonian (Rb) homozygotes 2n = 24 and heterozygotes 2n = 32. We ...
B chromosomes and Robertsonian fusions of Dichroplus pratensis (Acrididae): intraspecific support for the centromeric drive theory
(Karger, 2004-12)
We tested the centromeric drive theory of karyotypic evolution in the grasshopper Dichroplus pratensis, which is simultaneously polymorphic for eight Robertsonian fusions and two classes of B chromosomes. A logistic ...
Hexavalents in spermatocytes of Robertsonian heterozygotes between Mus m. domesticus 2n=26 from the Vulcano and Lipari Islands (Aeolian archipelago, Italy)
(Luigi Ponzio e figlio Editori, 2018)
© S. Berríos et al. 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 ...
Synaptic configuration of quadrivalents and their association with the XY bivalent in spermatocytes of Robertsonian heterozygotes of Mus domesticus
(2017)
BACKGROUND: The nuclear architecture of meiotic prophase spermatocytes is based on higher-order patterns of spatial associations among chromosomal domains and consequently is prone to modification by chromosomal rearrangements. ...
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 ...
Supernumerary chromosomes, Robertsonian rearrangement and multiple NORs in Corydoras aeneus (Pisces, Siluriformes, Callichthyidae)
(1988-01-01)
Cytogenetic studies in four samples of Corydoras aetteus from tributaries of the Tietê River in the upper Paraná System, Brazil (rivers Araquá, Corumbataí, Capivara and Alambari) evidenced a diploid number of 2n = 60 and ...
X monosomy and balanced Robertsonian translocation in a girl with Turner Syndrome
(Sociedade Brasileira de Genética, 2006-01-01)
We describe a case of X monosomy associated with a maternally inherited t(13;14) Robertsonian translocation in a girl with Turner syndrome. The girl's X chromosome was demonstrated to be maternally inherited, ruling out ...
SYNAPTONEMAL COMPLEX-ANALYSIS IN GOATS CARRYING THE 5/15 ROBERTSONIAN TRANSLOCATION
(Elsevier B.V., 1994-01-01)
Synaptonemal complexes were analysed by electron microscopy in 2 bucks heterozygous for the 5/15 Robertsonian translocation. The cis configuration (free homologous 5 and 15 chromosomes on the same side of the 5/15 translocated ...
