What is the unit of a genetic map?

Genome mapping is a method for identifying the location of a gene on a chromosome and the distances between genes. It can also describe the distances between different sites within a gene. 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.  Genome mapping can detect balanced and unbalanced structural variation, copy number changes, and haplotypes. It has the added benefit of being able to detect and ascertain the nature of more abnormalities than array, karyotyping, or... Show more

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. 
Genome mapping can detect balanced and unbalanced structural variation, copy number changes, and haplotypes. It has the added benefit of being able to detect and ascertain the nature of more abnormalities than array, karyotyping, or FISH. 
Genome mapping has promised many things, including discovering ancestral histories and how genes are involved in diseases.
