Portrait of Dr Mary Lyon in 2004 in the laboratory by Dr Lizzie Burns. It was while working on radiation hazards in 1961 that she discovered X-chromosome inactivation, for which she is best known, [16] and the phenomenon is sometimes known as Lyonization in her honour.
X-inactivation (also called Lyonization, after English geneticist Mary Lyon) is a process by which one of the copies of the X chromosome is inactivated in therian female mammals. The inactive X chromosome is silenced by being packaged into a transcriptionally inactive structure called heterochromatin .
Simultaneously, Mary F. Lyon began investigating manipulations of X-linked traits that had phenotypically visible consequences, particularly in mice, whose fur color is a trait intimately linked to the X chromosome.

Nonrandom X-inactivation leads to skewed X-inactivation. Nonrandom X-inactivation can be caused by chance or directed by genes. If the initial pool of cells in which X-inactivation occurs is small, chance can cause skewing to occur in some individuals by causing a bigger proportion of the initial cell pool to inactivate one X chromosome.
One spring day, Katherine, 10, and Sheila Lyon, 12, vanished without a trace. With their bodies not found after 50 years, this week, police and the FBI search returned to the land linked with ...
