Detailed explanation-1: -Gene mapping refers to the process of determining the location of genes on chromosomes. Today, the most efficient approach for gene mapping involves sequencing a genome and then using computer programs to analyze the sequence to identify the location of genes.

Detailed explanation-2: -Genetic mapping-also called linkage mapping-can offer firm evidence that a disease transmitted from parent to child is linked to one or more genes. Mapping also provides clues about which chromosome contains the gene and precisely where the gene lies on that chromosome.

Detailed explanation-3: -Genome mapping is used to identify and record the location of genes and the distances between genes on a chromosome. Genome mapping provided a critical starting point for the Human Genome Project.

Detailed explanation-4: –assigning/locating of a specific gene to particular region of a chromosome and determining the location of and relative distances between genes on the chromosome.

Detailed explanation-5: -There are two types of genome mapping approaches, physical mapping and genetic linkage mapping, in which distances are measured in base pairs and recombination frequency, respectively.
