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 ...

Sex chromosomes are chromosomes, or packages of DNA, that are found inside the nucleus of all of your cells. There are two different kinds: X and Y, which determine whether you’re biologically male ...

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 ...

Scientists discovered a new gene family on the Y chromosome of deer mice, challenging the belief that the chromosome only ...

“There’s nothing like a dame,” sang the Navymen in South Pacific. Not so, say physiologists. There are people who are something like a dame but are really men, or even a combination of male and female ...

The vast majority of cancer cells have too few or too many copies of some chromosomes, a state known as aneuploidy. But for decades, researchers have debated whether aneuploidy promotes the growth of ...

Translocations, in genetics, happen when chromosomes break and the pieces attach to other chromosomes. This mixing of genetic material has important results. The resultant chromosomes are lacking in ...

If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in ...

The frequency and distribution of chromosomal abnormalities and the impact of parental chromosomal aberration on the pregnancy outcomes of couples with recurrent pregnancy loss remains controversial.

Sister chromatid cohesion (SCC) is mediated by the cohesin complex and its regulatory proteins. To evaluate the involvement of a protein in cohesin regulation, preparations of metaphase chromosome ...

Robertsonian chromosomes (ROB) are a type of structurally variant chromosome that is created when two chromosomes fuse together to form an unusual bond. Found commonly in nature, these chromosomes are ...

System schematic for automatic detection of sister chromatid exchanges. Machine learning techniques have been used to develop a set of algorithms that can identify and count SCEs in microscopy images.
