The white recessive gene test identifies whether a bird carries the genetic variant responsible for producing the recessive white plumage trait. Through precise DNA analysis, this test determines if a bird is homozygous positive, heterozygous (carrier), or homozygous negative for the white recessive gene. These results help poultry breeders understand inheritance patterns, plan pairings responsibly, and predict possible plumage outcomes in future clutches.

Sample Collection

For best results, label paper envelopes with the sample number, species and bird ID printed on our order form. Place 2-3 freshly plucked feathers greater than 3cm in length, from each bird into each envelope. Alternatively, blood spotted on card can be provided. Allow any blood at the tip of the feather’s calamus, or on card, to dry before placing in the envelope.
