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 ...

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 ...

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 ...
