The chromosome associated with male development, which is the last mysterious piece of the human genome, has been fully sequenced by a team of more than 100 researchers around the world, including ...

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 ...

Some facts are taken for granted. In the case of genetics, we take for granted the knowledge that humans have 23 pairs of chromosomes, which encode everything from our appearance to our propensity for ...

Meiosis – the pairing and recombination of chromosomes, followed by segregation of half to each egg or sperm cell – is a major crossroads in all organisms reproducing sexually. Yet, how the cell ...

The Chromosomes Hiding in Specks of Lint Watch on (via SciShow) Tiny versions of chromosomes show up in things like birds, reptiles, and amphibians. These mysterious lint-like flecks may be the ...

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 ...

Each human cell contains 23 pairs of chromosomes that carry DNA within their nucleus. The X and Y chromosomes, commonly referred to as the sex chromosomes, are one such pair. They determine the ...

Scientists have confirmed that the Atlas blue butterfly carries the most chromosomes of any animal, with 229 pairs. Unlike duplication, its chromosomes split apart, reshaping its genome in surprising ...

New research at the University of Kentucky has confirmed that the presence of XX sex chromosomes increases the amount of fat circulating in the blood, which leads to narrowing of the arteries and ...

A juvenile rhesus macaque, a species of Old World monkeys. The rhesus macaque was one of 19 mammals included in a study reconstructing chromosome rearrangements during 105 million years of mammalian ...

The Atlas blue butterfly, also known as Polyommatus atlantica, has been genetically confirmed as having the highest number of chromosomes out of all multicellular animals in the world. This insect ...
