Detailed explanation-1: -A linkage map is a linear graphic representation of the sequence and relative distances of the various genes present in a chromosome.

Detailed explanation-2: -The order of genes on a chromosome can be determined by measuring the recombination frequencies. By finding recombination frequencies for different gene pairs, we can do gene mapping that shows the order of the genes on the chromosome.

Detailed explanation-3: -A linkage map (also known as a genetic map) is a table for a species or experimental population that shows the position of its known genes or genetic markers relative to each other in terms of recombination frequency, rather than a specific physical distance along each chromosome.

Detailed explanation-4: -… A karyotype is an individual’s complete set of chromosomes. The term also refers to a laboratory-produced image of a person’s chromosomes isolated from an individual cell and arranged in numerical order. A karyotype may be used to look for abnormalities in chromosome number or structure.

Detailed explanation-5: -With chromosome maps called idiograms, researchers can pinpoint the locations of genes and locate abnormal gene forms. Most cytogeneticists are skilled at identifying individual chromosomes based on their sizes, their shapes, and the banding patterns of their arms.
