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 ...

Researchers have uncovered a "selfish" X chromosome in the fruit fly Drosophila testacea that manages to distort inheritance in both sperm and eggs. "But until now, we've only ever seen a particular ...

When plants end up with the wrong number of chromosomes, the consequences are usually dire. Cells starved of, or overloaded ...

However, one plant — a South American beak-sedge called Rhynchospora tenuis — seems to represent a striking exception. Previous studies have reported that R. tenuis lacks crossover during male meiosis ...

Newswise — Changes in chromosome number are common in plants, but the direction of those changes is often difficult to reconstruct because ancestral forms are extinct or unknown. In Medicago, this ...

Researchers predict that having extra sets of chromosomes can both speed up and slow down the evolution of an organism, depending on the organism’s “fitness landscape.” Crop plants such as wheat and ...

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 ...
