Losing the Y chromosome seems to make cancer cells more aggressive in men and the phenomenon may even spread between cells.

More than 80% of early human embryos contain cells with an incorrect number of chromosomes—a phenomenon called aneuploidy.

Researchers from the University of Arizona have unveiled that coordinated Y chromosome loss in both cancer cells and immune cells may explain the worse prognosis in people with this alteration. The ...

A new tool generates and labels customized aneuploid cells in living tissue to observe the behavior of these cells in ...

The evolution of a new species by hybridization from two already described species without a change in chromosome number is very rare in the animal kingdom. So far, only a few accepted empirical ...

In all cultures examined the chromosome number was predominantly 46, as shown in Table 1, and in every case there was a normal female karyotype. A representative tissue section, metaphase and ...

Yet something else caught my eye in the data: there were numerous changes in the structures and numbers of nearly every chromosome. Instead of having two copies of each chromosome, as is typical for ...

Chromosomal variations involve larger-scale changes than genetic variations and may involve: differences in the number of chromosomes inside cells changes in the structure or function of a ...

It will now be possible to study specific and unique Y chromosome sequence patterns, such as the structure of the two satellites and the location and copy numbers of the genes. Even within the Y ...
