Answer:
a feature or quality belonging typically to a person, place, or thing and serving to identify them.
Explanation:
The right answer is gene mapping.
The act of mapping consists of determining the relative positions of the loci (genes or DNA sequences) on a chromosome. The binding maps are obtained from the recombination frequency between the loci. Physical maps are generally obtained by the use of in situ hybridization of cloned DNA fragments with metaphase chromosomes, or the use of somatic or hybrid irradiation hybrids.
