Genomic mapping is a field of study within genetics that focuses on identifying and mapping the location of genes and other DNA sequences on chromosomes. This can involve techniques such as DNA sequencing, restriction mapping, and genetic linkage analysis to determine the order and distance between genes on a chromosome. Genomic mapping is important for understanding the structure and organization of the genome, identifying disease-causing genes, and studying genetic variation within populations. It is also a critical step in the process of genome sequencing and assembly.
