Ferns, defined by large genomes, high chromosome counts, and pervasive aneuploidy as well as intraspecific polyploid ...

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 ...

Researchers at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have identified a mechanism that protects the female ...

Chromosomes are masters of organization. These long strings of DNA fold down into an ensemble of compact structures that keep needed parts of the genome accessible while tucking away those that aren't ...

In conjunction with University Medical Center Mainz, researchers at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have identified a mechanism that protects the female brain from genetic ...

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 ...

Scientists have decoded the Y chromosome in full for the first time. In a new article published Aug. 23 in Nature, scientists with the Telomere-to-Telomere, or T2T, consortium—a group of researchers ...

Scientists have achieved a genetic feat once thought impossible: removing an entire extra human chromosome using gene-editing ...

Cancer doesn’t evolve by pure chaos. Scientists have developed a powerful new method that reveals the hidden rules guiding how cancer cells gain and lose whole chromosomes—massive genetic shifts that ...

Agrobacterium tumefaciens magnified 15,000 times in an image captured earlier this year with a scanning electron microscope at Iowa State University's Roy J. Carver High Resolution Microscopy Facility ...
