Y linkage, also known as holandric inheritance (from Ancient Greek ὅλος hólos, "whole" + ἀνδρός andrós, "male"), [1] describes traits that are produced by genes located on the Y chromosome. It is a form of sex linkage. Y linkage can be difficult to detect.
All single-copy Y-linked genes are hemizygous (present on only one chromosome) except in cases of aneuploidy such as XYY syndrome or XXYY syndrome. Traits that are inherited via the Y chromosome are called Y-linked traits, or holandric traits (from Ancient Greek ὅλος hólos, "whole" + ἀνδρός andrós, "male"). [58]
•List of human protein-coding genes page 4 covers genes SLC17A8–ZZZ3 NB: Each list page contains 5000 human protein-coding genes, sorted alphanumerically by the HGNC-approved gene symbol. Follow the Python code link for information about updates to the list of genes on these pages.
The SHOX gene in the PAR1 region is the gene most commonly associated with and well understood with regards to disorders in humans, [17] but all pseudoautosomal genes escape X-inactivation and are therefore candidates for having gene dosage effects in sex chromosome aneuploidy conditions (45,X, 47,XXX, 47,XXY, 47,XYY, etc.).
Genetic linkage is the tendency of DNA sequences that are close together on a chromosome to be inherited together during the meiosis phase of sexual reproduction.Two genetic markers that are physically near to each other are unlikely to be separated onto different chromatids during chromosomal crossover, and are therefore said to be more linked than markers that are far apart.
The paper offers expression breadth, the number of tissue types in which the genes are expressed, as an example of a feature correlated to sex-biased genes. It is known that genes with limited expression (in only one type of tissue) generally evolve faster than those with a higher expression breadth, and sex-biased genes are often restricted in ...

Said 160 kb from chromosome 1 consisted of 5 genes and the 5-prime end of a sixth gene, these genes came from a locus in the same chromosome known to cause a condition called autosomal non-syndromic deafness type 49.
