Triploids play an important role in the polyploidization process and are considered a bridge between diploids and polyploids. To inform plant polyploidization research and polyploid breeding, it is important to explore chromosome behaviour ...
Comparative karyotype analysis provides cytogenetic evidence for the origin of sweetpotato [0.03%]

The origin of hexaploid sweetpotato [Ipomoea batatas (L.) Lam.] remains controversial. Comparative karyotype analysis is particularly useful in determining species relationships and the origin of polyploid species. In previous study, we dev...
A familial chromosome 4p16.3 terminal microdeletion that does not cause Wolf-Hirschhorn (4p-) syndrome [0.03%]

Chromosome 4p16.3 microdeletions are known to cause Wolf-Hirschhorn syndrome (WHS), which is characterized by a distinct craniofacial gestalt and multiple congenital malformations. The 4p16.3 region encompasses WHS critical region 1 (WHSCR1...
Cdk8 and Hira mutations trigger X chromosome elimination in naive female hybrid mouse embryonic stem cells [0.03%]
Cdk8和Hira的突变触发naive雌性杂种小鼠胚胎干细胞中的X染色体消除

Mouse embryonic stem cells (ESCs) possess a pluripotent developmental potential and a stable karyotype. An exception is the frequent loss of one X chromosome in female ESCs derived from inbred mice. In contrast, female ESCs from crosses bet...

The number of chromosomes varies tremendously across species. It is not clear whether having more or fewer chromosomes could be advantageous. The probability of non-disjunction should theoretically decrease with smaller karyotypes, but too ...
Prenatal diagnosis and genetic analysis of small supernumerary marker chromosomes in the eastern chinese han population: A retrospective study of 36 cases [0.03%]
汉族人群小额外染色体的产前诊断及遗传学分析：36例回顾性研究

Xiali Jiang et al.
Background: Small supernumerary marker chromosomes (sSMCs) are additional chromosomes with unclear structures and origins, and their correlations with clinical fetal phenotypes remain incompletely understood, which reduce...
The holocentricity in the dioecious nutmeg (Myristica fragrans) is not based on major satellite repeats [0.03%]
雌雄异体肉豆蔻(Myristica fragrans)中的全端性不是基于主要的卫星重复序列产生的

Holocentric species are characterized by the presence of centromeres throughout the length of the chromosomes. We confirmed the holocentricity of the dioecious, small chromosome-size species Myristica fragrans based on the chromosome-wide d...

Species frequently differ in the number and structure of chromosomes they harbor, but individuals that are heterozygous for chromosomal rearrangements may suffer from reduced fitness. Chromosomal rearrangements like fissions and fusions can...
A germline chimeric KANK1-DMRT1 transcript derived from a complex structural variant is associated with a congenital heart defect segregating across five generations [0.03%]
