To understand how the chocolate-gen works, please first read the information on this page
Well, if you understand how chocolate works, i will now explain how the Mottled-gen works, but it’s not very difficult because we have the beautifull scheme of Meg Woodhouse:
This scheme is paid by the donation of José Kramer
The mottled gene is called ‘recessive’. It means it has to be there in 2 doses, so 1 dosis from mom, 1 dosis from daddy.
But the Mottled gene is not really 100% recessive. In fact it’s pretty dominant. Why is it pretty dominant? Well, youngsters with 1 dosis of mottled will not be mottled but also not completely without mottling. Birds which are having 1 dosis of mottled are mostly very easy to recognize by their tiny little spots in the neck, their eye-colour, the spots on the skin of the feet and sometimes spots on brest. Please look at the pictures:
This hen is a (black-) mottled hen I bred in the past. She is mottled, so 2 doses.
How can you recognize a split-mottled?
This hen is a split mottled ( 1 dosis ). Look at the tiny little white spots. 
This chocolate cockerel is a split-mottled
Please look at the head ( tiny white spots in the neck and head, the light eyecolour and the 2-coloured beak.
Please look at the few white spots on the brest.
Please look at his lightcoloured legs with brown spots.
These girls are both chocolatemottled and sisters. The right one is much too white. After her first real moult she will be much whiter, maybe around 90%. The other one will be very well proportioned mottled after the first real moult.
