The Human Genome Project was a 13-year-long publicly funded project initiated in 1990 with the objective of determining the DNA sequence of the entire euchromatic human genome within 13 years. [ 8 ] [ 9 ] The idea of such a project originated in the work of Ronald A. Fisher , whose work is also credited with later initiating the project. [ 10 ]
Low-resolution physical mapping is typically capable of resolving DNA ranging from one base pair to several mega bases. In this category, most mapping methods involve generating a somatic cell hybrid panel, which is able to map any human DNA sequences, the gene of interest [clarification needed], to specific chromosomes of animal cells, such as those of mice and hamsters.

When printed, the human genome sequence fills around 100 huge books of close print. Genome projects are scientific endeavours that ultimately aim to determine the complete genome sequence of an organism (be it an animal, a plant, a fungus, a bacterium, an archaean, a protist or a virus) and to annotate protein-coding genes and other important genome-encoded features.

The Genome Project–Write (also known as GP-Write) is a large-scale collaborative research project (an extension of Genome Projects, aimed at reading genomes since 1984) that focuses on the development of technologies for the synthesis and testing of genomes of many different species of microbes, plants, and animals, including the human genome ...
There are two distinctive mapping approaches used in the field of genome mapping: genetic maps (also known as linkage maps) [7] and physical maps. [3] While both maps are a collection of genetic markers and gene loci, [8] genetic maps' distances are based on the genetic linkage information, while physical maps use actual physical distances usually measured in number of base pairs.
Although the 'completion' of the human genome project was announced in 2001, [2] there remained hundreds of gaps, with about 5–10% of the total sequence remaining undetermined. The missing genetic information was mostly in repetitive heterochromatic regions and near the centromeres and telomeres , but also some gene-encoding euchromatic ...
A genome map is less detailed than a genome sequence and aids in navigating around the genome. The Human Genome Project was organized to map and to sequence the human genome. A fundamental step in the project was the release of a detailed genomic map by Jean Weissenbach and his team at the Genoscope in Paris. [22] [23]
The field of genomics began to grow in the 1970s when new technology was discovered by A.M. Maxam and W. Gilbert, [4] and continued to advance with the widely recognized Human Genome Project. It was the application of the technology and strategies used in genomics to landscape genetics that created the field of landscape genomics. [3]
