In 2002, evolutionary biologist Jenny Graves shared a controversial calculation. The human Y chromosome, she wrote two years later in a commentary, "is running out of time." The male-determining sex ...

Researchers at Cardiff University have uncovered how a particularly severe form of DNA damage arises—shedding new light on ...

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 ...

Human cells have two copies of each chromosome, and this balance is essential for genes to be expressed in the appropriate ...

A simulated cell in the early stages of division. Left half shows membrane (green cubes), and ribosomes (yellow/purple) interwoven through in the cell’s chromosome (red). Right side shows all the ...

Autism spectrum disorder (ASD) is a neurological and developmental condition that can be diagnosed at any age, although the symptoms tend to appear in the first two years of a patient's life. ASD can ...

Researchers at a lab in Kansas City believe they have made a breakthrough discovery in understanding infertility.

For sexual reproduction to yield healthy offspring, newly generated oocytes—immature egg cells—must receive the correct amount of DNA after cell division. This process of segregating chromosomes ...

India, March 17 -- Selfish chromosomes bias genetic inheritance by manipulating the overdrive (Ovd) gene, a natural sperm quality control checkpoint.
