Recessive White (c/c) Genetic Test

c/c – Recessive white – Homozygous Recessive
C/c – Carrier – Heterozygous Carrier
C/C – Not recessive white – Homozygous Normal

Identify carriers, confirm masking, and make informed breeding decisions.

This PCR-based DNA test detects the recessive white allele (c) responsible for inhibiting pigment deposition in feathers, allowing breeders to distinguish between carriers, non-carriers, and visually white chickens caused by this gene.

Recessive white is a fully recessive, pigment-inhibiting mutation. Chickens that are c/c will appear white and can mask underlying color and pattern genetics. Chickens that are C/c are carriers and can produce white offspring when paired with another bird carrying the same allele.

This test does confirm:

Presence or absence of the recessive white allele (c)
Carrier status (C/c)
Genotype of visually white birds (distinguishes recessive white from other causes)

This test does NOT confirm:

Dominant white
Other white or dilution genes
Pattern or color hidden beneath white

Sample Type: Blood on the tip of a coffee filter or printer paper cut into a triangle. Please see our SAMPLING PAGE for instructions and desired amount of blood needed.
Turnaround Time: Results are typically back the same day samples are received at the lab if they arrive via USPS. Please allow 48 hours before reaching out about your results. We also ask that you refrain from reaching out to see if your samples have arrived. You will receive an email once your samples have been logged into our computer system here at the lab. Please purchase a tracking number for your convenience of knowing when your sample will arrive. Samples sent via FedEx or UPS will be logged into the computer and processed the following business day. Thank you for understanding.
