Recessive White Gene Test ©

The Recessive White Gene Test helps breeders identify whether a chicken carries the recessive white allele associated with white feathering.

This test is useful for breeders who want to confirm carrier status, better understand visually white birds, or make more informed breeding decisions. Because recessive white can mask other color and pattern genetics, DNA testing can help clarify whether the trait is present even when it is not visually obvious.

Possible result types may include:

c/c – Homozygous Recessive White
C/c – Carrier of Recessive White
C/C – Not Recessive White

This test can help confirm:

Presence or absence of the recessive white allele
Carrier status
Whether a visually white bird is genetically recessive white
Breeding decisions related to recessive white traits

This test does not confirm:

Dominant white
Other white or dilution genes
Hidden color or pattern genetics beneath white feathering
Other unrelated feather color modifiers

After purchasing testing credits, customers will enter their sample details through the customer portal, generate a Batch Slip, label their samples, and mail them to the laboratory. Once the batch has been processed, results will become available through the customer dashboard.

Sample Type:

Blood sample collected on the tip of a coffee filter or clean printer paper cut into a small triangle. Please visit our Sample Collection page for step-by-step instructions before mailing your samples.

Turnaround Time:

Results are typically processed after samples are received and logged by the laboratory. Customers will receive updates through the customer portal and/or email once samples are received and when results are ready.
