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.
Binary Alignment Map (BAM) is the comprehensive raw data of genome sequencing; [1] it consists of the lossless, compressed binary representation of the Sequence Alignment Map-files. [2] [3] BAM is the compressed binary representation of SAM (Sequence Alignment Map), a compact and index-able representation of nucleotide sequence alignments. [4]
developed to run under the Unix operating system, using X-Windows for graphics, with a local copy of the database files; Development on AceDB appears to have ceased as the interface is still using old technology and many of the sites that originally used it have upgraded to newer software.

The GeneLoc suit member presents an integrated human chromosome map, which is very important for designing a custom-made capture chip, based on data integrated by the GeneLoc algorithm. GeneLoc includes further links to GeneCards, NCBI's Human Genome Sequencing, UniGene, and mapping resources. [7] [13]
Each chromosome map in BacMap is extensively hyperlinked and each chromosome image can be interactively navigated, expanded and rotated using navigation buttons or hyperlinks. All identified genes in a BacMap chromosome map are colored according to coding directions and when sufficiently zoomed-in, gene labels are visible. Each gene label on a ...
Three chromosomal abnormalities with ISCN nomenclature, with increasing complexity: (A) A tumour karyotype in a male with loss of the Y chromosome, (B) Prader–Willi Syndrome i.e. deletion in the 15q11-q12 region and (C) an arbitrary karyotype that involves a variety of autosomal and allosomal abnormalities.

In molecular biology, genome architecture mapping (GAM) is a cryosectioning method to map colocalized DNA regions in a ligation independent manner. [ 1 ] [ 2 ] It overcomes some limitations of Chromosome conformation capture (3C), as these methods have a reliance on digestion and ligation to capture interacting DNA segments. [ 3 ]
Chromosome jumping (or chromosome hopping) was first described in 1984 by Collins and Weissman. [1] At the time, cloning techniques allowed for generation of clones of limited size (up to 240kb), and cytogenetic techniques allowed for mapping such clones to a small region of a particular chromosome to a resolution of around 5-10Mb.
