an abstract mathematical representation of genetic loci that conserves order of loci, which are spaced in such a way that the distances are algebraically additive; conventionally, a map is scaled so that as distances between loci become smaller the ratio of the map distance to the value of the recombination fraction approaches 1 and independently assorting loci are infinitely far apart.

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