Inheriting a normal and intact number of chromosomes in germ cells, egg and sperm, is essential for the preservation of all species. With increasing age, the risk of the egg cell not inheriting the ...

Starting as a single cell, organisms undergo millions of generations of divisions to ultimately generate the bones, heart, brain and other components that make up a living being. The mainspring within ...

A long-standing mystery in plant evolution has now been brought into sharper focus. Using chromosome-specific painting, researchers traced how chromosome number changed within the genus Medicago, ...

Jumping genes and X chromosome disease risk: a new Science study finds that X-chromosome inactivation makes the silenced X ...

Duchenne muscular dystrophy (DMD) occurs as a result of genetic changes on the X chromosome. If someone has a gene change that can cause DMD, their children may inherit that change. DMD is a ...

For decades, the Y chromosome—one of the two human sex chromosomes—has been notoriously challenging for the genomics community to sequence due to the complexity of its structure. Now, this elusive ...

Inheriting a normal and intact number of chromosomes in germ cells, egg and sperm, is essential for the preservation of all species. With increasing age, the risk of the egg cell not inheriting the ...
