When cancer cells in male patients and immune cells in their tumors both lose the Y chromosome, those patients tend to ...

Men have lost most of the genes originally included on the Y chromosome during evolution, but those genes essential for survival have persevered, new research finds. Many of the remaining Y ...

Chromosome 2 is the second largest of the 46 chromosomes found in human cells. Chromosome 2 spans 243 million base pairs and makes up around 8% of the total DNA present within our cells.

The first attempt to determine the building blocks of our genetic code took place 20 years ago, but there were still significant gaps left in the sequences of all 23 pairs of human chromosomes.

The chromosome associated with male development, which is the last mysterious piece of the human genome, has been fully sequenced by a team of more than 100 researchers around the world, including ...

The Y chromosome in primates — including humans — is evolving much more rapidly than the X chromosome, new research on six primate species suggests. For instance, humans and chimpanzees share ...

The Y chromosome is what distinguishes biological males from females. It determines male fertility, including sperm production, and typically is used to determine paternal lineage for tracking ...
