Individual genetic maps in a given species are:
genetically similar
genetically identical
genetically dissimilar
not useful in species analysis

genetically similar

Explanation:

Genetic maps or chromosome maps of a species are representations of the positions and relative distances of the gene locus or genetic markers, that is, the region occupied by a gene along the chromosomal molecule that transmits hereditary characteristics. Since individuals of the same species have genetic similarities to each other, we can use the concept of genetic maps to assert that individual genetic maps in a given species are genetically similar.
