Genetic linkage

From Biology-Online Dictionary

Genetic linkage

(Science: genetics) 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.

See: linkage equilibrium, linkage disequilibrium.
