How are these unique sex chromosomes formed? "The sex of a somatic cell as highly differentiated as a neurone may be detected ...

Researchers have uncovered a "selfish" X chromosome in the fruit fly Drosophila testacea that manages to distort inheritance in both sperm and eggs. "But until now, we've only ever seen a particular ...

A study in mice suggests how chromosome inactivation may protect girls from a type of autism disorder inherited from their father's X chromosome. Females inherit two copies of the X chromosome, one ...

Researchers have identified inherited genetic variants that may predict the loss of one copy of a woman's two X chromosomes as she ages, a phenomenon known as mosaic loss of chromosome X, or mLOX.

A new study published in Nature Genetics has uncovered surprising patterns in how cells utilize maternal and paternal X-chromosomes across different organs and tissues. The research, conducted by the ...

X-chromosome inactivation varies across different areas of brains. Here, fluorescent imaging data from a mouse reveal where the father’s X chromosome is most active (white) and least active (blue). A ...
