linkage (redirected from Linkages)

linkage /link·age/ (lingk´ij)

1. the connection between different atoms in a chemical compound, or the symbol representing it in structural formulas; see also bond.

2. in genetics, the association of genes having loci on the same chromosome, which results in the tendency of a group of such nonallelic genes to be associated in inheritance.

3. in psychology, the connection between a stimulus and its response.

link·age (lngkj)

n.

An association between two or more genes such that the traits they control tend to be inherited together.

linkage,

n 1. in genetics, the location of two genes on the same chromosome such that they are typically transmitted as a cohesive unit during meiosis.
2. in psychology, the relationship between a response and its stimulus.

n See polymerization, cross.

linkage, sex,

n the inheritance of certain characteristics that are determined by genes located in the sex chromosomes.

linkage

1. the connection between different atoms in a chemical compound, or the symbol representing it in structural formulae. See also bond.

2. in genetics, the association of genes having located on the same chromosome, which results in the tendency of a group of such nonallelic genes to be associated in inheritance (linkage disequilibrium). Called also syntenic group.

disequilibrium linkage

the inheritance of two alleles together at a higher than expected frequency.
