DNA Testing – Mottling Gene

Mottling Gene (Mo) PCR Test

Determine if your birds carry the Mottling gene that creates beautiful speckled patterns!

The Mottling gene (Mo) in chickens is responsible for creating attractive white spots on feathers, giving birds a speckled, mottled, or pied appearance. This simple PCR test detects whether your bird carries zero, one, or two copies of the mottling gene—providing valuable information for breeding decisions.

Test results:

• No Mottling gene (wild-type) → solid plumage

• One copy of Mottling (carrier) → partial mottling or hidden in certain breeds

• Two copies of Mottling → fully mottled, speckled feather pattern
