Researchers from the University of Tennessee Health Science Center have made a foundational discovery about chromosome biology through their work on the first-ever human pangenome reference. Published ...

Every second, millions of cells in your body divide in two. In the space of an hour, they duplicate their DNA and grow a web ...

In what might be a surprise for some, the male sex chromosome is far more complex than its female counterpart. This is why it’s taken scientists so long to work out exactly what makes a male a male.

During sexual reproduction, haploid gametes (i.e. eggs and sperm) are generated from diploid precursors through the specialized cell division of meiosis. Meiosis reduces ploidy by following one round ...

Cell division is a process of remarkable precision: during each cycle, the genetic material must be evenly distributed between the two daughter cells. To achieve this, duplicated chromosomes, known as ...

Highly challenging to sequence and long overlooked, the human Y chromosome's contributions to health and disease remain largely unknown. A new paper that presents, for the first time, the complete ...

A biology professor at a community college in San Antonio says he was fired for teaching students that sex is determined by X and Y chromosomes. He said he was told his lessons were ‘offensive and ...
