Would he have coloured breeding or do some solid bred horses have colourd sheaths
yes somewhere he will have a coloured gene, the gene may not come out in any of his youngstock or their youngstock, you may never see a coloured sired by him but he will definatly have a coloured gene somewhere in his breeding
Do you mean his sheath or his penis? My bay stallion has a pink patch on his penis, which I believe is common for solid colour stallions
Many Highland stallions have a white/pink patch on their penis, and they are considered a solid color?
yea his penis i was just trying to be polite sorry
I couldn't comment whether or not the patch means he is genetically coloured or not, or whether or not he should be bred from - but if he IS coloured he must carry at least one, if not a pair of coloured genes and this means he would have at least 50% chance of passing on his colouring. It would be very unusual for a coloured stallion to never throw a coloured foal, the chances of that are miniscule.
Very easily tested for though.

The coloured gene is dominant, so if he has a coloured gene, he will be coloured.
yes you are right, but he doesnt have to be fully coloured i.e a coloured sheath, and a coloured gene is not dominant unless both mare and stallion are coloured or he is homozygous. as the coloured gene would be recognised as C and a black would also be recongised as a B therfore there would be 50/50 chance of getting a solid black or coloured. colour genetics are so hard to get your head round it has took me 33 years lol one of my mares is a coloured and the stallion i used was dark bay and my foal is a realy rich chesnut...... so therfore somewhere eigther at the back of my stallion or mare their is a chesnut.
Not quite. Tobiano is a dominant gene so if the horse had it it would be expressed but there is a chance of such minimal expression that only a couple of white hairs grow in the mane for example. A horse homozygous for tobiano will pass the gene to all offspring.
Chestnut is recessive to bay and black so can be hidden through generations but has to come from both sides.
Colour genetics is easy - getting the results you want is not.
DNA testing is not expensive.
If you don't know his breeding why isn't he a gelding?
To answer the question - many horses have white splashes on the belly. This could fall on the sheath.
maybe hes amazing in his own right, or they breed him and have looked after a stallion befor and like having him like that. maybe they know one generation back. maybe they only know his mums line so worth breeding from but dnt no if there are any coloured on his dads side. maybe hes a rescue case and better of sorting out lots of other things first. lots of reasons y u dnt just cut his balls of.
But 10,000 more reasons why you WOULD geld him rather than leave him entire!
