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 23rd chromosome base pair contains what are known as our sex chromosomes. For most females, this pair contains two X chromosomes, while for most males, it contains one X chromosome and one Y ...

Is the Y chromosome disappearing and could it affect the future of men? Experts say the reality is far more complex and far ...

Men tend to lose the Y chromosome from their cells as they age. But because the Y bears few genes other than for male determination, it was thought this loss would not affect health. But evidence has ...

The phenomenon now known as mosaic loss of chromosome Y, or mLOY, first emerged when researchers noticed that some men’s blood cells showed a missing Y in standard genomic data. A Primary study on ...

The humble Y chromosome may be the smallest chromosome in the mammalian genome (and getting even smaller), but it is mighty: genes on the Y chromosome are critical for fertility in males. In a new ...

Prognosis is poor for tumours with Y-chromosome loss. Examining the interplay between cancer and immune cells sheds light on potential mechanisms. Read the paper: Concurrent loss of the Y chromosome ...

The Y chromosome is among the smallest in the human body and carries the fewest genes. Researchers are paying renewed attention to its role in cancer—specifically, what happens when it vanishes. Women ...

The runt of the chromosome litter may have more to its bite than simply determining male sex. According to a study published June 2 in The American Journal of Human Genetics, loss of the Y chromosome ...

The Y chromosome is a never-ending source of fascination (particularly to men) because it bears genes that determine maleness and make sperm. It's also small and seriously weird; it carries few genes ...

Newly generated, complete genomes for the sex chromosomes of six primate species may inform conservation of these endangered species and shed light on sex-related genetic diseases in both humans and ...
