Genetic linkage


/ˈliNGkij/

Noun, pl. genetic linkages

1. The property of genes of being inherited together. (wiktionary.org)

2. The tendency of genes that are located proximal to each other on a chromosome to be inherited together during meiosis. Genes whose loci are nearer to each other are less likely to be separated onto different chromatids during chromosomal crossover, and are therefore said to be genetically linked. (wikipedia.org)

3. The term refers to the fact that certain genes tend to be inherited together, because they are on the same chromosome. Thus parental combinations of characters are found more frequently in offspring than nonparental. Linkage is measured by the percentage recombination between loci, unlinked genes showing 50% recombination. (biology-online.org)

4. Traits that tend to be inherited together as a consequence of an association between their genes; all of the genes of a given chromosome are linked (where one goes they all go). (wordnetweb.princeton.edu)
