Lineages

A Lineage represents a breeding relationship between two parent Cycle Plants and their offspring.

Lineages are available within Breeding Projects and allow you to:

• Assign Parent A and Parent B

• Add one or more offspring plants

• Define the traits you want to track

• Record trait expressions for the parents and offspring

• Generate Punnett square predictions for possible trait outcomes

Note

Lineages are only available for Breeding Projects.

Lineages Section

Each Lineage is displayed in a collapsible section on the Project page.

Select the Lineage name to view:

• Parent A

• Parent B

• Assigned offspring

• Lineage Traits

• Recorded trait expressions

• Trait prediction controls

The Lineage table uses badges to identify the plants and expressions:

• A identifies Parent A.

• B identifies Parent B.

• O identifies an offspring plant.

• D identifies a dominant expression.

• R identifies a recessive expression.

Select a parent or offspring name in the table to view additional plant information.

Lineage Fields

Field	Required	Description
Lineage Name	Yes	The name used to identify the Lineage.
Parent A	Yes	The Cycle Plant assigned as Parent A.
Parent B	Yes	The Cycle Plant assigned as Parent B.

How to Add a Lineage

1. Open the navigation menu and select Projects.

2. Select the applicable Breeding Project.

3. Find the Lineages section.

4. Select Lineage.

5. Complete the Lineage Fields.

6. Select Save.

The new Lineage will appear in the Lineages section.

How to Delete a Lineage

1. Open the navigation menu and select Projects.

2. Select the applicable Breeding Project.

3. Find the Lineage under the Lineages section.

4. Select the Lineage name to expand it.

5. Select the Lineage trash button.

6. Confirm the deletion.

Lineage Traits

Lineage Traits are the plant characteristics you want to track and predict within a Lineage.

Examples may include:

• Leaf shape

• Flower color

• Height

• Bud density

• Internodal spacing

Each Lineage Trait contains a dominant and recessive expression.

For example, a Leaf Shape Trait could use:

• Broad as the dominant expression

• Narrow as the recessive expression

You can select a predefined Trait or enter a custom Trait.

Lineage Trait Fields

Field	Required	Description
Predefined Trait	No	An existing Trait that can automatically fill the Trait name and available expressions.
Trait	Yes	The name of the characteristic being tracked.
Dominant	Yes	The expression associated with the dominant allele.
Recessive	Yes	The expression associated with the recessive allele.

How to Add a Lineage Trait

1. Open the applicable Breeding Project.

2. Find the Lineage under the Lineages section.

3. Select the Lineage name to expand it.

4. Select Trait.

5. Select a predefined Trait or enter a custom Trait name.

6. Enter the dominant expression.

7. Enter the recessive expression.

8. Select Save.

The Trait will be added as a column in the Lineage table.

Offspring

Offspring assignments connect Cycle Plants to the Lineage as the result of the cross between Parent A and Parent B.

A Lineage can contain multiple offspring plants. This allows you to compare how the tracked Traits are expressed across siblings from the same cross.

How to Add Offspring

1. Open the applicable Breeding Project.

2. Find the Lineage under the Lineages section.

3. Select the Lineage name to expand it.

4. Select Offspring.

5. Select one or more Cycle Plants.

6. Select Save.

The selected plants will appear in the Lineage table with an O badge.

Tracking Trait Expressions

The Lineage table displays the parents and offspring in rows and the Lineage Traits in columns.

GroBase uses Plant Trait information from the related Cycle Plants when it is available.

Trait information remains synchronized between the Lineage and the related Cycle Plant:

• Changes made to a Cycle Plant’s Plant Traits can update its expressions within a Lineage.

• Changes made to parent or offspring expressions within a Lineage can update the related Cycle Plant’s Plant Traits.

Each Trait cell can be set to:

• The dominant expression

• The recessive expression

• Neutral

Neutral can be used when the observed expression should not be marked as dominant or recessive.

How to Update Trait Expressions

1. Open the applicable Breeding Project.

2. Find the Lineage under the Lineages section.

3. Select the Lineage name to expand it.

4. Find the parent or offspring row in the Lineage table.

5. Select the applicable Trait cell.

6. Select the observed expression.

7. Repeat for any other plants or Traits you want to update.

8. Select Update Traits.

Dominant expressions display a D badge. Recessive expressions display an R badge.

Punnett Square Predictions

GroBase uses Punnett square logic to predict possible trait inheritance based on the expressions recorded for Parent A and Parent B.

Each prediction may display:

• The dominant and recessive allele expressions

• Possible Parent A and Parent B genotypes

• A Punnett square

• Genotype probabilities

• Possible offspring outcomes and percentages

These results are predictions based on the information recorded in the Lineage. They do not guarantee which expression an individual offspring plant will display.

How to Generate Trait Predictions

1. Open the applicable Breeding Project.

2. Find the Lineage under the Lineages section.

3. Select the Lineage name to expand it.

4. Add the Lineage Traits you want to evaluate.

5. Record the applicable expressions for Parent A and Parent B.

6. Select Update Traits.

7. Select Predict Trait Outcomes.

8. Select a Trait result to view its prediction details.

A message is displayed when there is not enough information to generate a prediction.
