TLDR
Comparisons suggest that the dimorphic X and Y chromosomes of eutherian mammals evolved from a homomorphic pair in a common ancestor by gradual reduction of the Y, accompanied by a spreading of inactivation into newly unpaired regions of the X.About:

Dating the evolutionary radiations of the true fungi
Mary L. Berbee,John W. Taylor +1 more
TL;DR: A relative time scale for the origin and radiation of major lineages of the true fungi is constructed, using the 18S ribosomal RNA gene sequence data of 37 fungal species, and then calibrate the time scale using fossil evidence.

X-chromosome inactivation and cell memory
Arthur D. Riggs,Gerd P. Pfeifer +1 more
TL;DR: The aspects of X-chromosome inactivation that are relevant to cell memory are reviewed and the various molecular mechanisms that have been proposed to explain its occurrence are discussed, with emphasis on DNA methylation and a recently proposed mechanism that depends on the timing of replication.

The pseudoautosomal regions of the human sex chromosomes.
TL;DR: Gene pairs that are active on the X and Y chromosomes are suggested as candidates for the phenotypes seen in numerical X chromosome disorders, such as Klinefelter's (47,XXY) and Turner's syndrome (45,X).

Gene Action in the X -chromosome of the Mouse ( Mus musculus L.)
TL;DR: Ohno and Hauschka1 showed that in female mice one chromosome of mammary carcinoma cells and of normal diploid cells of the ovary, mammary gland and liver was heteropyKnotic and suggested that the so-called sex chromatin was composed of one heteropyknotic X-chromosome.

Preferential inactivation of the paternally derived X chromosome in the extraembryonic membranes of the mouse
Nobuo Takagi,Motomichi Sasaki +1 more
TL;DR: In an effort to determine the embryonic stage at which the X chromosome initiates differentiation in famale mouse embryos heterozygous for Cattanach's translocaton, it was found that the mosaic composition was consistently biased in extraembryonic membranes, whereas it was not necessarily so in the embryonic body.

A gradient of sex linkage in the pseudoautosomal region of the human sex chromosomes.
François Rouyer,Marie-Christine Simmler,Christophe Johnsson,Gilles Vergnaud,Howard J. Cooke,Jean Weissenbach +5 more
TL;DR: Three independent pseudoautosomal loci are linked to sex determination at frequencies which define a gradient of linkage that indicates that X/Y recombination results from a single obligatory meiotic crossing-over in the pseudoautOSomal region.
