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 ...

Small plastic or metal bits at the end of shoelaces, known as aglets, prevent laces from unraveling and protect them from wear and tear. Similarly, chromosomes are capped by telomeres—specialized ...

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.

New chromosome-level evidence suggests Medicago evolution followed a more complex, and surprising path, than previously ...

Genome duplication probably gave biodiversity a decisive evolutionary boost. A Chinese-German research team led by Axel Meyer ...

A long-standing mystery in plant evolution has now been brought into sharper focus. Using chromosome-specific painting, researchers traced how chromosome number changed within the genus Medicago, ...

Duchenne muscular dystrophy (DMD) occurs as a result of genetic changes on the X chromosome. If someone has a gene change that can cause DMD, their children may inherit that change. DMD is a ...

Adrenoleukodystrophy is a rare condition associated with abnormalities in myelin, the white matter that protects nerve fibers in the spinal cord and brain. It occurs due to a mutation on the X ...

Some genes just don’t play fair. Researchers have uncovered a ‘selfish’ X chromosome in the fruit fly Drosophila testacea that manages to distort inheritance in both sperm and eggs. “Researchers have ...
