Color blindness in females is much less common than in males. Specific genetic mutations can cause it, and these mutations vary depending on the chromosomes present. Learn more.

Color blindness, or color vision deficiency, is more common in males. This is due to how parents pass down a chromosome associated with the male sex.

The Y chromosome can disappear over time in human males, which may introduce a number of health problems. While the exact trigger for such degeneration is unknown, environmental factors can play a ...

The Y chromosome has seen significant changes over the course of human evolution. "In comparison to the X, the Y is tiny. There are only 45 genes on the Y chromosome, ...

Chromosome pairs carry genes from each parent, which determine a person’s physical characteristics, like their height or eye color. The 23rd pair of chromosomes determine whether a person is ...

Scientists fully sequence the Y chromosome for the first time, uncovering information that could have implications for the study of male infertility and other issues.

Two decades after the human genome sequence was completed, researchers have finally finished a map of the piece that makes males distinct. The Y chromosome is what distinguishes biological males ...

The Y chromosome, along with the X chromosome, is often discussed for its role in sexual development. While these chromosomes play a central role, the factors involved in human sexual development are ...
