Since the 1 920s, when researchers began to study chromosomes, the analysis of human chromosomes has presented a particularly tough technological challenge, simply because there are so many of them.

The Cytogenetics Laboratory performs chromosome analysis, fluorescence in situ hybridization (FISH), and array comparative genomic hybridization (array CGH) on cells prepared from a wide variety of ...

Karyotype analysis includes complete chromosome analysis of at least twenty metaphases with at least two cut karyotypes. The presence or absence of an acquired clonal chromosomal abnormality may aid ...

In female mammals, one of the two X chromosomes is usually inactive and forms the so-called Barr body. The image shows a cell nucleus with the Barr body marked in green. Unlike men, who carry one X ...

Until recently, about half of the human Y chromosome was missing from the reference genome. Now, scientists have sequenced this chromosome from end to end. Credit: National Human Genome Research ...
