The male-determining sex chromosome has lost 97 percent of its ancestral genes in the last 300 million years. If that rate ...

Scientists remain divided over whether the human Y chromosome will eventually vanish. But clinicians say the real concern ...

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 ...

Human biological sex is determined by the sex chromosomes X and Y. In most cases, females possess two X chromosomes, while males have one X and one Y. However, there is some evidence that the Y ...

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 ...

The human Y chromosome, responsible for male sex determination, has forfeited 97% of its ancestral genes over the past 300 million years. Evolutionary biologist Jenny Graves cautioned it "is running ...

Researchers discovered that a long-misunderstood protein plays a key role in helping chromosomes latch onto the right “tracks ...

Neil Hunter, a professor in the Department of Microbiology and Molecular Genetics, has discovered a crucial step in how chromosomes stay connected during the development for egg cells and sperm, ...

UC San Diego researchers uncover enzyme behind cancer genome chaos, pointing to potential therapies for aggressive tumors.

Cell division is essential for the correct transmission of genetic information. Each chromosome within a plant contains a ...

University of California San Diego researchers have discovered the enzyme responsible for chromothripsis, a process in which ...
