Y linkage

In mammals, Y-linkage, also known as holandric inheritance, is the determination of a phenotypic trait by an allele (or gene) on the Y chromosome.

Because the Y-chromosome is small and does not contain many genes, few traits are Y-linked, and Y-linked diseases are rare. Since the only humans who have a Y chromosome are males, Y-linked traits are passed only from father to son, with no interchromosomal genetic recombination.

Y-Chromosome deletions are a frequent genetic cause of male infertility. Having hairy ears was once thought to be a Y-linked trait in humans, but that hypothesis has been discredited.

Genes known to be contained on the Y chromosome

As of the year 2000, a number of genes were known to be Y-linked, including:

Linkage (software)

In programming languages, particularly the compiled ones like C, C++, and D, linkage describes how names can or can not refer to the same entity throughout the whole program or one single translation unit.

The static keyword is used in C to restrict the visibility of a function or variable to its translation unit. This is also valid in C++. (C++ 98/03 deprecated this usage in favor of anonymous namespaces, but is no longer deprecated in C++ 11.) Also, C++ implicitly treats any const namespace-scope variable as having internal linkage unless it is explicitly declared extern, unlike C.

A name's linkage is related to, but distinct from, its scope. The scope of a name is the part of a translation unit where it is visible. For instance, a name with global scope (which is the same as file-scope in C and the same as the global namespace-scope in C++) is visible in any part of the file. Its scope will end at the end of the translation unit, whether or not that name has been given external or internal linkage.

Linkage (album)

Linkage (styled as LINKAGE) is the third album by J-pop singer Mami Kawada. It was released on March 24, 2010 under Geneon Universal Entertainment. This album contains thirteen tracks which includes her singles "PSI-Missing", "Masterpiece" and "Prophecy". This album also contains the ending theme for the original video animation anime series Shakugan no Shana S entitled "All In Good Time" and a cover song of The Cranberries' hit song entitled "Dreams".

This album came in a limited CD+DVD edition (GNCV-1017) and a regular CD-only edition (GNCV-1018). The DVD contains the music video for the titular track "Linkage".
