New research reveals rapid changes in the Y chromosome across humans and Great Apes, uncovering significant genetic variability and evolutionary insights.

Recent research has produced detailed genomes of sex chromosomes for six ape species, showing significant variability and evolution on the Y chromosome. This work aids in understanding reproductive ...

Researchers have sequenced the complete X and Y chromosomes of several great ape species, revealing significant evolutionary variations, especially in the rapidly evolving Y chromosome. This study, ...

Sex chromosome abnormalities, including missing or extra X and Y chromosomes, can be difficult to detect in ancient DNA as it slowly erodes over time or becomes contaminated. Scientists have now ...

For many years, the human Y chromosome was terra incognita. Scientists completed the genetic sequences of other chromosomes, the threadlike structures that hold an organism’s DNA. But more than ...

Scientists have fully sequenced the Y chromosome for the first time, uncovering information that could have implications for the study of male infertility and other health problems.

This arrangement results in humans having twenty-three pairs of chromosomes, while other great apes possess twenty-four pairs. The Y chromosome posed a challenge due to its relatively intricate ...
