    What's the genetic difference between "Mille Fluer" and Speckled Sussex (mottled red columbian) ?


    I know they are NOT the same thing, I want to know what the SS is missing that the MF has....

    Theres not much difference, SS are Mille Fleur, Mille Fleur as in dUccles is Mottleing on a Buff Columbian bird and SS are mottling on a Red Columbian bird. Its the same, the SS just have the additional mohagany genes.

    Quote:So, if you cross back a SS to a buff columbian roo, then the F1 back to a SS, will you eventually get a Mille Fleur color patten in the Sussex? What is recessive here??

    The PATTERN i the same; mottled columbian. What is lacking in hte mille fleur is the mahogany gene that enhances the colour of the red. The speckled sussex may also be missing gold dilution genes that are present in the speckled sussex.

    Quote:So, can one get a mille fleur mottling on a blue or black bird? Or only on mahogany and buff/golden bird?

    In blue or black, the black band between the base color and white obviously wouldn't show up, so you only have white mottled birds. You can have the tri-color pattern in lavender, it's called porcelain like in the porcelain d'uccles.

    So, this is fascinating stuff! I am crossing my fingers I get one Lav roo from the LAv Ameraucana order I made, coming to me next month. If I cross the roo with the SS hen, I could or will get the porcelain coloration? Or probably I should be asking about the %'s, right??? Thank you!

    Quote:Nope! Trust me, I've looked into this! (Using Orloffs instead of SS, though.)

    The Mahogany factor that gives these birds the red base messes it all up. Mille Fleur is buff-based, and the porcelain relies on that. [​IMG]

    I THINK there may be some true buff-based Mille Fleur LF Cochins, but most LF speckled/spangled birds over here are mahogany based.

    You would first have to spend a couple of years breeding a true mille fleur using a buff bird with the SS. It's a long process! I have the recipe written down in my notebooks for later. [​IMG]

    Sussex look to be wheaten but the down color is not wheaten. The down color looks like a false wild type. This difference in down color may be caused by a modifier or a different E locus allele. there is a difference- but being able to say exactly what the difference is hypothetical.

    based upon the birds color- both the red and speckled sussex carry mahogany and autosomal red. i have not carried out any experimental crosses with the sussex. my opinion is based upon my work with rhode island red.
