Detailed explanation-1: -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-2: -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-3: -Geneticists use maps to describe the location of a particular gene on a chromosome. One type of map uses the cytogenetic location to describe a gene’s position. The cytogenetic location is based on a distinctive pattern of bands created when chromosomes are stained with certain chemicals.

Detailed explanation-4: -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.
