Genes are segments of DNA (deoxyribonucleic acid) that are located inside every human cell. The DNA inside each cell is tightly coiled in structures called chromosomes. Each chromosome contains a ...

The loss of the Y chromosome in tumour cells is linked to poor outcomes for people with cancer 1, but this genetic alteration might also compromise immune cells that would otherwise fight the disease.

Increased risk for autism appears to be linked to the Y chromosome, a study has found, offering a new explanation for the greater prevalence of autism in males. Increased risk for autism appears to be ...

Sex is determined in a variety of different ways throughout the animal kingdom. In mammals, it is determined genetically, not by temperature, as it can be in reptiles. Typically, females have two X ...

“We’ve known that tiny fragments of ancient DNA can survive for long periods of time,” said Dr. Marcela Sandoval-Velasco of the Center for Evolutionary Hologenomics at the University of Copenhagen and ...

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 ...

The molecules that silence a woman’s second X chromosome can confuse the immune system, a new study suggests. By Carl Zimmer Women are much more likely than men to have their immune system turn ...

A chromosome is a DNA molecule that contains genetic material. Sex chromosomes are chromosomes that affect your sexual anatomy and reproductive development. Most of us were raised with the idea that ...

The Y chromosome is perhaps the most puzzling part of the human genome. Associated with male development, it is chock-full of repetitive and inverted stretches of DNA, a hurdle that makes it ...
