Sex determination at birth is decided on the chromosomes the baby has. A female has two X chromosomes, whereas a male has one X and one Y chromosome. According to Medline Plus, in every cell, humans ...

The Y chromosome is inherited only through the paternal line. Sons receive their Y chromosome exclusively from their father.

In what might be a surprise for some, the male sex chromosome is far more complex than its female counterpart. This is why it’s taken scientists so long to work out exactly what makes a male a male.

Researchers at the Crick have uncovered which genes on the Y chromosome regulate the development of sperm and impact fertility in male mice. This research could help us understand why some men don't ...

Every human cell has a pair of chromosomes that give your body a blueprint for how to grow and develop starting as a single cell inside a uterus. But in a new study from the Cedars-Sinai cancer center ...

The Telomere-to-Telomere (T2T) consortium, co-led by UC Santa Cruz Genomics Institute Associate Director Karen Miga and National Institutes of Health Genomics Research Institute Senior Investigator ...

Newly generated, complete genomes for the sex chromosomes of six primate species — produced by an international collaboration led by researchers at Penn State and the National Human Genome Research ...

Women may think of men as primitive, but new research indicates that the Y chromosome — the thing that makes a man male — is evolving far faster than the rest of the human genetic code. A new study ...

For any mammal, the loss of the Y chromosome should mean the loss of males and the demise of the species. So how the Amami spiny rat manages without a Y chromosome has puzzled biologists for decades.
