Using chromosome-specific painting, researchers traced how chromosome number changed within the genus Medicago, which ...

Sophisticated techniques offer insights into the unusual features of the inactive X chromosome in female mammalian cells RIKEN cell biologists have provided an unprecedented glimpse into the ...

The good news is two branches of rodents have already lost their Y chromosome and have lived to tell the tale. A new paper in Proceedings of the National Academy of Science shows how the spiny rat has ...

When cancer cells in male patients and immune cells in their tumors both lose the Y chromosome, those patients tend to experience poorer outcomes than patients without Y chromosome loss, according to ...

Research confirmed that the 'Y' chromosome, which is essential for sex determination in humans, is actually shrinking in size over time due to genetic decay. This could potentially lead to a future ...

In female mammals, one of the two X chromosomes is usually inactive and forms the so-called Barr body. The image shows a cell nucleus with the Barr body marked in green. Unlike men, who carry one X ...

In a time when what defines gender is being questioned and discussed, a new study reveals that single changes in DNA make ...

Humans typically have 46 chromosomes arranged in 23 pairs. One of these pairs determines biological sex at the time of conception. Males usually have one X chromosome and one Y chromosome. The ...

The Y chromosome is unlike other chromosomes in the human genome. It does not regularly recombine with a matching partner, making it genetically isolated. Over evolutionary time, this isolation has ...

The Y chromosome, critical for male sex determination, has been losing genetic material and might vanish in the future. Studies in some rodents indicate that species can survive by evolving new ...
