Women are born with two X chromosomes and inherit one from each parent. But in every cell of their body, just one X chromosome is needed – so the other is randomly inactivated. Some cells use only a ...

In about one out of every 800 people, two chromosomes fuse together to form an unusual bond. These are known as Robertsonian chromosomes. It's a mystery that has long stumped scientists. Now, ...

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 ...

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 ...

Sex is determined in a variety of different ways throughout the animal kingdom. In mammals, it is determined genetically, not by temperature, as it can be in reptiles. Typically, females have two X ...

Robertsonian chromosomes are large chromosomes that form when the long arm of a chromosome breaks and fuses with another chromosome. They are the most common type of chromosome rearrangement in humans ...

A condition known as Robertsonian translocation occurs when the long arms of two chromosomes join together. The characterization of the fully sequenced and assembled fused chromosomes reveals a common ...

Neil Hunter, a professor in the Department of Microbiology and Molecular Genetics, has discovered a crucial step in how chromosomes stay connected during the development for egg cells and sperm, ...

A nearly gapless genome sequence of the echidna, an egg-laying mammal with multiple sex chromosomes, helps researchers to track genomic reorganization events that gave rise to a highly unusual sex ...
