Sex Chromosome Haploty**
Chromosomes X and Y have been true homologues and have evolved differently over the years. The Y chromosome has shrunk to about 60 Mb in size as a...

Ring Chromosome 18
Although it is ultra-rare, ring chromosome 18 (RC18) is one of the most commonly occurring congenital ring chromosomes (RCs). This is likely due to...
-
Chromosome Bandings and Recognition
Chromosome banding can be defined as the lengthwise variation in staining properties along a chromosome stained with a dye. Chromosome banding became...
-
Ring Chromosome 17
Ring chromosome 17 (RC17) that replaces a normal chromosome 17 homologue is extremely rare, and only about 20 RC17 cases were reported in literature....
-
Ring Chromosome Y
Cases with ring chromosome Y (RCY) were detected using karyoty**, fluorescence in situ hybridization (FISH), Southern blotting, PCR analysis, and...

Characterizing genetic variation on the Z chromosome in Schistosoma japonicum reveals host-parasite co-evolution
BackgroundSchistosomiasis is a neglected tropical disease that afflicts millions of people worldwide; it is caused by Schistosoma, the only dioecious...

Y chromosome-linked variation affects locomotor activity in male Drosophila melanogaster and is robust to differences in thermal environment
Although containing genes important for sex determination, genetic variation within the Y chromosome was traditionally predicted to contribute little...
-
Ring Chromosome 6
Ring chromosome 6 (RC6) is a rare constitutional structural abnormality that generally occurs during meiosis or early post-zygotic mitosis. Most of...
-
Ring Chromosome X
Cases with ring chromosome X (RCX) were detected using karyoty**, fluorescence in situ hybridization (FISH), Southern blotting, PCR analysis, and...
-
Ring Chromosome 22
About 250 cases of ring chromosome 22 (RC22) have been reported in the literature. Approximately 90% of RC22 cases have a deletion of the terminal...
-
Ring Chromosome 7
In general, ring chromosomes (RCs) are among the rarest constitutional chromosomal aberrations. Hereby, chromosome 7 comprises only 23 postnatal and...

Types of Chromosome Mutations
Structural chromosome aberrations or chromosome mutations represent apart from aneuploidies the most frequent pathologic findings in applied...
-
Ring Chromosome 2
Ring chromosome 2 (RC2) in the context of a karyotype with a modal number of 46 chromosomes is an infrequently documented chromosomal structural...

The Y-Chromosome Lineage Variation in Ancient and Modern Populations of the Sakha (Yakuts)
AbstractThis review presents the results of paleogenetic studies on the ancient population of Yakutia in the Middle Ages. The diversity of...

Genetic Databases and Online Ring Chromosome Registry
The rapid adaptations of genomic technologies into genetic testing require knowledge-based genetic databases and disease registries in various...

Genome-wide analysis reveals allelic variation and chromosome copy number variation in paromomycin-resistant Leishmania donovani
In the absence of adequate diagnosis and treatment, leishmaniasis remains a major public health concern on a global scale. Drug resistance remains a...

X-chromosome influences on neuroanatomical variation in humans
The X-chromosome has long been hypothesized to have a disproportionate influence on the brain based on its enrichment for genes that are expressed in...

A complete chromosome substitution map** panel reveals genome-wide epistasis in Arabidopsis
Chromosome substitution lines (CSLs) are tentatively supreme resources to investigate non-allelic genetic interactions. However, the difficulty of...

The Importance of Monitoring Non-clonal Chromosome Aberrations (NCCAs) in Cancer Research
Cytogenetic analysis has traditionally focused on the clonal chromosome aberrations, or CCAs, and considered the large number of diverse non-clonal...

A Paradoxical Role for Somatic Chromosomal Mosaicism and Chromosome Instability in Cancer: Theoretical and Technological Aspects
Somatic chromosomal mosaicism, chromosome instability, and cancer are intimately linked together. Addressing the role of somatic genome variations...
