UCSF researchers found that brain cells age more quickly when they rely solely on the X chromosome inherited from a female's ...

Gene editing techniques may one day allow for the removal of the extra chromosome that causes Down syndrome, early ...

People who have one of several well-documented medical conditions do not have only XX or XY chromosomes, which typically correspond with female and male sexes, respectively. Those conditions include ...

Gene editing techniques may eventually allow trisomy to be treated at the cellular level, according to an in vitro ...

Chromosomes contain hundreds to thousands of genes, which are sections of DNA located at specific points on a chromosome. The Y chromosome is an exception, only containing a few dozen genes.

However, there is some evidence that the Y chromosome is being phased out of the evolutionary pipeline, and could one day disappear altogether — potentially giving rise to a new sex gene in the ...

A high-quality genome assembly of Silene latifolia was generated by researchers at CNRS/Université Claude Bernard Lyon 1 and ...

Some fish have a gene that determines sex, but not a whole chromosome. Even in humans, the X/Y sex chromosome system isn’t as ...

Decades ago, researchers showed that Down syndrome (also known as trisomy 21), was caused when individuals carried an extra ...

Researchers at the Francis Crick Institute studying male mice engineered with different Y chromosome deletions have uncovered which genes on the mouse Y chromosome regulate the development of ...
