    Foal
    Just got the results

    I am still waiting on the roan zygosity test but I got the red factor and agouti results. Here is the results. I am really clueless when it come to color genetics and was wondering what this means. I am planning on breeding her and here is the stallys genetics EeA & aDd

    Red-Factor Result:
    E/e - Both black and red factors detected. Either E or e transmitted to offspring. Basic color is black, bay or brown in the absence of other modifying genes.

    Agouti Result:
    A/a - Only recessive allele detected. Black pigment distributed uniformly. Basic color is black in the absence of other modifying genes.

    Thanks for any info.

    It means your horse is heterozygous for extension, which results in a black base colour (black, bay, brown). So basically not a colour that has a red base, such as chestnut.

    The second part means that your horse has no copy of the agouti gene present, so has no black restriction. This means it is a black based horse that is not bay or brown. So without any other genes tested for, I am going to assume that your horse is a black horse that can pass on a red gene.

    I hope you typed that wrong because if she is Aa she is bay not black and that doesn't jive with the info they gave you.

    So this is what we know: (I think the stallion's agouti status may be wrong, he doesn't look brown dun to me, and definitely isn't bay dun. But I ran with the info given. If I am correct, and he doesn't have any agouti gene, then there is no chance the foal could be bay or brown.)

    EeAaDdrr

    X

    EeaaddRr (for the sake of full possibility, I have assumed that your mare is hetero for roan, see below for more).



    The possible extension for the foal:

    25% EE - black

    50% Ee - black

    25% ee - red

    Possible agouti: Please note that agouti only acts on a black base coat, so a red horse won't change depending on agouti status.

    25% Aa - bay or brown

    75% aa - black

    Dun:

    25% Dd - dun

    75% dd - not dun

    Roan:

    25% Rr - Roan

    75% rr - not Roan
    If your mare turns out to be homozygous, these roan chances would change to 100% Rr - Roan.



    Possible colours from this cross:

    Black
    Bay
    Brown
    Chestnut
    Black roan
    Bay roan
    Brown roan
    Chestnut roan
    Black dun
    Bay dun
    Brown dun
    Chestnut dun
    Black dun roan
    Bay dun roan
    Brown dun roan
    Chestnut dun roan

    This is copy and pasted from the results they sent me

    Red-Factor Result:
    E/e - Both black and red factors detected. Either E or e transmitted to offspring. Basic color is black, bay or brown in the absence of other modifying genes.

    Agouti Result:
    A/a - Only recessive allele detected. Black pigment distributed uniformly. Basic color is black in the absence of other modifying genes.

    And I want to breed her to the stally below her picture and this is what the stallys owner told me about his genetic EeA AND aDd she also told me that he is hetrozygous for dun and black and that he carries a seal gene

    where did you have this test done?

    Anywhere that I have ever seen it done if they are telling you the results they would have it as a/a. A/a means that the horse has one copy of an agouti gene...

    Just reread the email and the agouti is a/a don't know why when I copy and pasted it that it changes to a big A sorry for the confusion.
