GenXplore - Overview


This Module Is In Alpha. Check back here or contact us at for more information.

GenXplore is the KDXplore plug-in that enables users to search though specimen and pedigree data for genotypes.

From GenXplore, the database can be queried on the basis of different search criteria for certain individuals (genotypes).

After completing a search, the genotype pedigree, detailed parentage information, cross information and phenotypic information can be viewed.

GenXplore is also aimed at cross design which can be performed after a list of individuals is created. When a cross is designed in GenXplore the user will be warned if the cross has already been made.

Main Window

To access GenXplore, navigate to the KDXplore Main Window and then select the gen_explore_btn GenXplore Button. This will open the GenXplore Plug-in which will look like the image below:

Genotype Genealogy Tree

The GenXplore Plug-in can create a genealogy tree for any selected genotype ID. The following instructions outline how to do this:

Generating a Genealogy Tree for Selected Genotypes

Generating a Genealogy tree for Selected Genotypes 1/2
Step Action
1. By selecting a Genotype from the Genotype table and selecting the tree_btn button at circle1, the panel below will be populated with the Genealogy tree structure or ancestry of the selected genotype appearing in area circle2.
2. Undocking the panel, by selecting the expand_btn button seen in area circle3, provides a closer view.

Generating a Genealogy Tree for Selected Genotypes

Generating a Genealogy Tree for Selected Genotypes 2/2
Step Action
3. Controls for the genealogy tree can be seen in area circle4 and area circle5. The controls in area circle4 have zoom control, whether to pan when dragged or select nodes, display the tree in radial format and save the tree to PNG file. The top controls also contain a legend for what the shape of nodes in the tree represent, and the colour. The shape of the nodes and the colour in this instance represent the known (or unknown) sex of the nodes of the tree, when they were used to create progeny (also seen) in the tree.
4. Controls at the bottom of the panel seen in area circle5 allow the user to set what criteria, size and colour should be represented as. E.g. the size of each node in the tree could be representative of the # of crosses it was involved in, or maybe how many ancestors it has (length of line). The controls in area circle5 also contain options for the naming of nodes, e.g. whether to display ID, name of genotype or acronym.
5. To the furthest left of the controls in circle5 is a selector for what level of ancestry to show. In the instance shown here the tree is very large. This can be reduced by only showing 5 generations (as seen below).

Changing Genealogy Tree Depth

The genealogy tree that is generated will automatically show 10 levels of depth. The image and steps below outline how to change the depth of the tree.

Changing Genealogy Tree Depth

Changing Genealogy Tree Depth
Step Action
1. Enter the desired amount of tree depth such as the level of ‘5’ as shown in circle1. Nodes can also be selected and dragged manually around the panel area.
2. Select the Choose option in circle2.

Genealogy Tree Options

Once genotypes are selected, right-clicking anywhere will present a number of options as seen below:

Genealogy Tree Options

From the options the user can:

  • Export selected genotypes to CSV format
  • Add selected genotypes to the list in the genotype table
  • Collect genotypes for trial/nursery design.
  • Cross genotypes as female (Automatically adds to crossing table - see section 12.)
  • Cross genotypes as male (Automatically adds to crossing table - see section 12.)
  • Change the colour scheme used for node rendered (When a numeric genotype info is chosen for node colour, the colour scheme used to display it is set here).

Genotype Cross Information

The genealogical history of any Genotype crosses can be shown in the Cross Information Panel as seen below:

Genotype Cross Information

  • circle1 Crosses Tab displays the overall cross information for the selected genotype.
  • circle2 Cross Information Panel displays the overall cross information including total crosses and total back/test crosses.
  • circle3 Crosses Panel is a list of crosses that the selected genotype has been involved in. The resulting genotypes (By name and ID) can also be seen here.
  • circle4 Back/Test Crosses Panel is a list of back/test crosses for the selected genotype. Note that the Crosses Panel will not contain these entries.

Genotype Trait Information

Some genotypes may have trait information attached to them. To display the trait information, the user will need to search for, and select a trait, and then follow the instructions below:

Genotype Trait Information

Displaying Trait Information
Step Action
1. To display phenotypic data for the selected genotype select the Trait Values Tab in area circle1.
2. The Traits and respective values for the selected genotype will display in area circle2. Selections from this table will display the trait description in area circle3.
3. Trial information for the selected genotype will be visible from this screen also in the panel in area circle4.

Cross Designer

The GenXplore Plug-in gives users the ability to design crosses between various genotypes. After searching for, and selecting genotypes in the Search Panel, genotypes can be dragged into the Crossing Panel. After selecting genotypes for crossing, the below instructions will demonstrate how to create the cross.

Designing Crosses In GenXplore

Designing Crosses In GenXplore
Step Action
1. Navigate to the Make Crosses tab by selecting at circle1.
2. The genotypes selected for crossing can will be visible at area circle2 and circle3 after being dragged to those locations. Genotypes to-be-crossed as female are displayed in the left table and male genotypes are in the right table.
3. The cross_btn at circle4, when selected checks each cross has not been previously made and generate the names for subsequent intermediate child entries in the lower area circle5.
4. Attempting a cross that has already been made will display a warning dialog that can be seen in the image below. Crosses made previously will also display in the table in area circle5.

Duplicate Crosses

Rank and Expected Crosses

The concept of rank and expected crosses are that the genotypes chosen for crossing have an intended rank or importance.

For each parent genotype, crosses will be performed with each corresponding genotype of the opposite sex with the same rank, if expected crosses is larger than 0. Expected crosses then corresponds to how many ranks below the genotype will cross with genotypes of the corresponding sex.

Rank and Expected Crosses Cross Designer

Rank and Expected Crosses Cross Designer
Step Action
1. Rank of genotypes for crossing can be adjusted by selecting a genotype in either parent list and using the arrows seen in area circle1.
2. Expected crosses for genotypes can be adjusted by selecting a genotype in either parent list and entering the expected crosses values in area circle2.
3. Preset values for Diallel and Half-Diallel can be set by selecting the check boxes in area circle3.
4. Once parameters are set, the cross_btn Cross Button seen in area circle4 can be selected to perform the crosses.


For a less advanced crossing setup see the following section.

Punnet Square Crosser

The Punnet View allows the users to cross genotypes but has a simpler display to choose male and females to cross. The below instructions outline how to use this view.

Punnet Square Crosser

Crossing with Punnet View
Step Action
1. Selecting the button with the filter_btn Filter Button seen in area circle1 of the crossing panel will open the Cross Editor Window at circle2.
2. Inside this dialog seen in area circle3 are the selected genotypes for crossing. X-axis is female entries. Y-axis is male entries. By selecting cells in this matrix, you are selecting crosses to be performed.
3. In area circle4 the options for including a back cross and test cross can be checked.
4. Once crosses have been designed, the Cross Button seen in area circle5 can be selected to perform the crosses.

What To Do With Generated Progeny

Generated progeny can be used in the Trial Design Plug-in.
