portions, which would act as a boundary between these two segments. The G-banding comparisons of the Neo-X chromosomes of other Sigmodontinae taxa revealed a similar banding pattern, suggesting that the autosomal segment in the Neo-X can be shared among the Sigmodontinae lineages with a XY1Y2s...

Rumex hastatulus is the North American endemic dioecious plant with heteromorphic sex chromosomes. It is differentiated into two chromosomal races: Texas (
In-situ hybridization with (TTAGGG) n (all-human-telomeres probe) did not detect any telomeric interstitial regions (ITS), indicating a possible loss of terminal segments of the chromosomes involved in the neo-Y formation. 展开 关键词: Brachyhypopomus gymnotid heterochromatin sex chromosomes ...
In many species, sex is determined by a system based on X and Y chromosomes, the latter having lost much of their genetic activity. Y chromosomes have evol... B Charlesworth - 《Current Biology》 被引量: 1007发表: 1996年 Improved telomere detection using a telomere repeat probe (TTAGGG)n...
the p.Arg551Cys alteration was found in heterozygosity in one healthy control in ExAC database.27 As none of the variants was of paternal origin, we performed haplotype analysis using 42 microsatellite markers on 10 different chromosomes, which confirmed paternity and thus de novo occurrence of c...
(Giemsa, C-banding and AgNORs) and molecular methodologies (fluorescence in situ hybridization) and chromosome microdissection, indicated that a translocation between distinct acrocentric chromosomes bearing rRNA genes, accompanied by deletions in both chromosomes, might have originated the neo-Y chromosome...
Dog ERAP1 and ERAP2 haplotypes were shared by Caninae with karyotypes consisting of 76 acrocentric autosomes and a pair of metacentric sex chromosomes (Reimann et al., 1999). These species include the dog, gray wolf, coyote and jackal. Only two ERAP1 and one ERAP2 haplotypes found in ...
RCC2, also known as TD-60, was first identified as a novel human mitosis-specific autoantigen that localizes at the centromeres of prophase chromosomes [6]. Emerging evidence indicates that RCC2 is essential for cell cycle progression, as its depletion inhibits cell proliferation and arrests ...
The reduction of the chromosome number from 48 in the Great Apes to 46 in modern humans is thought to result from the end-to-end fusion of two ancestral non-human primate chromosomes forming the human chromosome 2 (HSA2). Genomic signatures of this event
