Detailed explanation-1: -Definition. A genetic map (also called a linkage map) shows the relative location of genetic markers (reflecting sites of genomic variants) on a chromosome.

Detailed explanation-2: -Sturtevant then worked out the order and the linear distances between these linked genes, thus forming a linkage map. In doing so, he computed the distance in an arbitrary unit he called the “map unit, ” which represented a recombination frequency of 0.01, or 1%.

Detailed explanation-3: -Summary. Linked genes are located on the same chromosome. Sex-linked genes are located on a sex chromosome, and X-linked genes are located on the X chromosome. The frequency of crossing-over between genes is used to construct linkage maps that show the locations of genes on chromosomes.

Detailed explanation-4: -A genetic map, also known as a linkage map, is a chromosome map of a species that shows the position of its known genes and/or markers relative to each other, rather than as specific physical points on each chromosome.

Detailed explanation-5: -Gregor Johann Mendel, the “father of genetics” founded the science of genetics. He worked with seven characteristics of 14 varieties of the garden the pea plants (Pisum sativum) which led him to the discovery of the Laws of inheritance which later came to be known as Mendel’s Laws of Inheritance.
