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 ...

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 ...

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 50 ...

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 ...

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, ...

Researchers used CRISPR to change the number of chromosomes in Arabidopsis by fusing chromosome arms, reducing the genome ...

Triploidy is a condition that affects 1% to 3% of pregnancies. It’s when a developing baby has an extra set of chromosomes, the thread-like structures that carry DNA. A triploidy pregnancy usually ...
