AutoSOME: a clustering method for identifying gene expression modules without prior knowledge of cluster number [PDF]

open access: goldBMC Bioinformatics, 2010
Background Clustering the information content of large high-dimensional gene expression datasets has widespread application in "omics" biology. Unfortunately, the underlying structure of these natural datasets is often fuzzy, and the computational ...

A New Cytotype of the Iranian House Mouse, Mus musculus Linnaeus, 1758 (Rodentia: Muridae), in Birjand Region, Eastern Iran: Implications for the Evolution of Sex-Autosome Translocations [PDF]

open access: greenIranian Journal of Animal Biosystematics, 2016
The highly conserved morphology and chromosomal structures of house mouse, Mus musculus, provides a good model for chromosomal studies. Sex-autosome translocations is one of the rarest chromosomal rearrangements among mammals and therefore sex-autosome ...

Neo-X-Linked Chromosome Polymorphism: Cytogenetic Insights from Passalites nemorivagus (Mammalia, Cervidae) [PDF]

open access: yesAnimals
Chromosomal instability plays a significant role in karyotype evolution and speciation in mammalian groups with notable intraspecific chromosomal variation. The Cervidae family, known for its rapid karyotypic evolution due to chromosomal fragility, shows

Worse than nothing at all: the inequality of fusions joining autosomes to the PAR and non-PAR portions of sex chromosomes [PDF]

open access: yesPeerJ
Chromosomal fusions play an integral role in genome remodeling and karyotype evolution. Fusions that join a sex chromosome to an autosome are particularly abundant across the tree of life.

New Insights on Chromosome Diversification in Malagasy Chameleons [PDF]

open access: yesAnimals
In this work, we performed a preliminary molecular analysis and a comparative cytogenetic study on 5 different species of Malagasy chameleons of the genus Brookesia (B. superciliaris) and Furcifer (F. balteautus, F. petteri, F. major and F. minor). A DNA

Genomic evidence reveals three W-autosome fusions in Heliconius butterflies.

open access: goldPLoS Genetics
Sex chromosomes are evolutionarily labile in many animals and sometimes fuse with autosomes, creating so-called neo-sex chromosomes. Fusions between sex chromosomes and autosomes have been proposed to reduce sexual conflict and to promote adaptation and ...

Evolution of a Multiple Sex-Chromosome System by Three-Sequential Translocations among Potential Sex-Chromosomes in the Taiwanese Frog Odorrana swinhoana

open access: yesCells, 2021
Translocation between sex-chromosomes and autosomes generates multiple sex-chromosome systems. It happens unexpectedly, and therefore, the evolutionary meaning is not clear.
