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 ...

Chromosomes unfold and refold each time cells divide. A study by Schooley et al. demonstrates that chromosome-intrinsic and cytoplasmic factors uniquely contribute to interphase chromosome structure, ...

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, ...

Sex-linked inheritance is a stark exception to Mendel’s Laws of Heredity. Here we discuss how the evolution of heteromorphic sex chromosomes (mainly the Y) has been shaped by the intricacies of the ...

For many years, the human Y chromosome was terra incognita. Scientists completed the genetic sequences of other chromosomes, the threadlike structures that hold an organism’s DNA. But more than 50 ...

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 ...

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 ...
