15-06-13 Researchers in the University of Georgia's Regenerative Bioscience Center are visually capturing the first process of chromosome alignment and separation at the beginning of mouse development. The findings could lead to answers to questions concerni...

14-12-08 In a new study, published in Science, researchers at Uppsala University demonstrate an association between smoking and loss of the Y chromosome in blood cells. The researchers have previously shown that loss of the Y chromosome is linked to cancer....

14-04-25 Despite a well-documented history of dramatic genetic decay, the human Y chromosome has over the course of millions of years of evolution managed to preserve a small set of genes that has ensured not only its own survival but also the survival of me...

14-03-19 A new study from the University of Southampton has provided scientists with a better understanding of why chromosome errors are high in women's eggs. It is estimated that up to 60 per cent of eggs are affected by errors in how their chromosomes divi...

13-03-19 Buried for 100,000 years at Xujiayao in the Nihewan Basin of northern China, the recovered skull pieces of an early human exhibit a now-rare congenital（先天的） deformation that indicates inbreeding might well have been common among our ancestors,...

12-12-28 New York University biologists have identified how a vital（至关重要的） protein is loaded by others into the centromere（着丝粒） , the part of the chromosome that plays a significant role in cell division. Their findings shed new light on genome r...

12-08-07 Two new studies offer insight into sex chromosome evolution by focusing on papaya（木瓜） , a multimillion dollar crop plant with a sexual problem (as far as growers are concerned) and a complicated past. The findings are described in two papers in...

11-09-27 New research presented at the European Society for Paediatric（儿科的） Endocrinology（内分泌学） meeting has found a genetic region that may control testicle development in the fetus. Men have XY sex chromosomes, and the development of testes is th...

10-05-14 Chromosome 22q11 deletion syndrome（综合症） (also known as DiGeorge syndrome) is the most common human chromosome（染色体） deletion syndrome, having an estimated incidence（影响，发生率） of at least one in 4,000 live births. It has a range of sev...
