In 2002, evolutionary biologist Jenny Graves shared a controversial calculation. The human Y chromosome, she wrote two years ...

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 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 upwards ...

Tatiana Schlossberg, the youngest granddaughter of President John F. Kennedy, recently revealed she was diagnosed with ...

Scientists have decoded the Y chromosome in full for the first time. In a new article published Aug. 23 in Nature, scientists with the Telomere-to-Telomere, or T2T, consortium—a group of researchers ...

Higher yields, greater resilience to climatic changes or diseases—the demands on crop plants are constantly growing. To ...

Cancer cells acquire genetic anomalies that allow them to grow and proliferate unchecked. Researchers have now found another difference between cancer cells and normal cells: the X chromosome, ...

A new study by researchers at the University of Wisconsin–Madison provides the first empirical evidence connecting the ...

New research shows that the male X chromosome is silenced in some types of cancer. Researchers evaluated how a certain gene affects the male X chromosome in cancer cells. Experts explain why these new ...

In many sexually dimorphic species, a mechanism is required to ensure equivalent levels of gene expression from the sex chromosomes. In mammals, such dosage compensation is achieved by X-chromosome ...
