    grey stallion (born chestnut, grey hetro)


    liver chestnut mare (homo chestnut)

    What colour could the foal be???

    I thought it would be 75% chestnut, 25% grey...... colour calculator says 50/50

    yeh I know grey is dominant.... but doesnt the stallion have a 50/50 chance of passing it on, and the mare no chance...?

    I have had a couple of foals from both grey parents be solid colour - both parents hetro grey.

    ohh the beauty of genetics haha
    i really have no idea :p
    but i remember doing all the hetro and homo testing for human genetics haha and the chances of passing on eye colour and diseases ect
    i guess its all the same in the end

    .... sorry this was pointless :confused:

    Grey is totally different to the colour the foal will be

    ie it will be born black or red?

    Grey is something that happens to that colour and you have a 50% chance of it going grey.

    edited as just read sire was born chestnut....chestnut sire x chestnut dam = only possible option of chestnut foal (ee)

    then 50% chance of it going grey or not

  10. Homozygous for red?:confused:';'
    Homozygous means that a horse can only produce a color base it is homozygous for.:)
    Any red horse bred to a homozygous for black horse will produce a black base foal. It means that your mare can't be "homo liver";) (she is a product of both red parents so she is just red based).
    In your case you have 50/50 chance of a red or a red that will grey out.:)

    ta guys :)

    dams sire and dams dam were both chestnut.

    sires sire was grey (born black), sires dam grey no other details... sires sires dam black, sires sires sires grey

    PS sires dam just produced solid chestnut filly - full sister to the 'sire'

    thanks guys!

    Doesn't that mean the grey is then homo :confused: if both parents grey ';'

    idk how that stuff works though LOL

    My understanding is the foal would definitely be born a chestnut, but also definitely grey out. ';'

    My girl is hetero grey, she has 1 grey parent (born bay I think) and one brown parent. I thought homo grey is both parents being grey, which in your boys case they are.

    argh confusing
  13. not necessarily B&T
    if even 2 parents were grey a foal can be GRGR (homozygous for grey) or GRgr(heterozygous).:)*

    yep I have had some born from two grey parents solid thank god lol!

    so the consensus is I have 50/50 chance of grey and chestnut?
  15. Yep:) a foal will be born red, then it will either stay red or will grey out:}
