I was wondering whether anyone could determine the probable colour of a foal. The sire is a bay - his sire is a bay, dam is a chestnut. The dam is a palomino - her sire is a palomino, dam is a chestnut. Any guesses as to what colour this ( as yet theoretical ) foal might be?

In fact, some breeds don't recognize palomino as a color. (Never say palomino to an Arabian owner, we call them 'bright chestnuts') Bay is a dominant, chestnut is recessive. To get chestnut the foal needs to inherit one gene for the color from EACH parent. To get Bay the foal only needs to inherit one gene for the color from one parent, the other gene would be chestnut. Since the sire is bay but he must carry recessive chestnut, he would give one chance in two of passing on the bay gene. Since the dam is palomino, she carries two genes for chestnut, one pale and one normal. So, you have two chances in four of getting a bay, one chance to get a regular chestnut and one to get a palomino. I've simplified this a little but this is your chances. It's really a little more complicated than this; I think that there is another gene involved that causes the paleness of the palomino. I do know that if you breed a palomino to a palomino you usually get a cremora (very pale almost white, NOT acceptable in palomino circles.) BTW, I bred my grey mare to a bay stallion and got a chestnut... The mare was recessive chestnut and so was the stallion. I had one chance in eight of getting a chestnut. (Grey is dominant and so is bay) I'm breeding my chestnut this year but quite by coincidence the stallion is also a chestnut so I know what color I am getting. Well, not actually by coincidence, they have some bloodlines in common. Anyway, color is not a factor in this breeding, I'm going for strengthening of the particular bloodlines and, hopefully, an future show horse. (The bloodlines are noted for looks, personality and performance.) B c ------------ | | | c | Bc | cc | | | | ----------- | | | p | Bp | cp | | | | -----------

I just wanted to thank everyone who responded to my query about horse colour. Though a bit confusing, I found it very interesting. I definitely hadn't considered the possibility of a buckskin!! Thanks again, Sarah Burger School of MIS Massey Univerity New Zealand

I used to have a golden buckskin. He was so flashy looking with his black mane and tail and black legs.
