The Marker Details windows will be displayed when you click on a marker name on a physical or genetic map.

Marker Details window: Basic Properties tab

There are four tabs in this example: Basic Properties, All Locations, Sequences, and Related Annotations. Markers typically have at least the first two tabs (Basic Properties and All Locations) but additional information available for a marker is variable. Click the links below for more information.

Basic Properties Tab

The fields displayed on the Basic Properties tab are described below.

Marker ID

This ID uniquely identifies the marker in the database. Markers, especially from different authors, can have identical names, but the MARKER_ID is guaranteed to be unique.

Type

Markers can have different types like SNP, SSR, AFLP, RFLP, etc. Sometimes the marker type can be used to filter the genetic maps to make them more readable (see Gene and Gene Data Track Information).

Location

Position of the marker on the given map. Genetic maps use cM (centiMorgan) as a distance unit.

Source

Institution that produced the marker or alternatively the database source for the information.

Assay Type

Assay method type used to follow the marker.

Source Organism

The species of origin of the marker.

Map Organism

The species DNA map.

Map Set

The map set for the map.

Map

The specific map used to display the marker; typically the chromosome map.

Mapping Score

The value obtained from linkage calculations.

Names

All known synonyms of the marker.

Description

The text information about the marker.

Marker Qualifiers

The Marker Qualifiers panel has a table of name-value pairs for attributes of the marker. The Mapping Qualifiers panel also has a table of name-value pairs about the mapping of the marker. The actual content will vary with the particular organism and marker.
