Golden Horses

I had to look up equine coat colour genetics (Wikipedia) to find out the chances of what colour Habib would throw when matched to various mares. (Although colour importance ranks last in what I am looking for in a foal, I still find it fun and I do like the dilutes.)

Akpay is a bay (E)
Darginka is a bay (E) with a dilute gene (Ccr), which lightens the brown coat so she ends up as a buckskin.
Pagoda is a palomino (e, Ccr). (Diluted chestnut)
Habib is a perlino (E) with two dilute genes (CcrCcr), which lightens to a whitish coat colour.
Basically, by adding a creme gene:

Bay -> buckskin -> perlino
Chestnut -> palomino -> cremello
Black -> smoky black -> smoky creme

Another good site on animal genetics has a color coat calculator:
(I’ve used homozygous genes for the solids as I just wanted a simple estimate.)

Perlino x

• Bay: 88% buckskin, 6% palomino/smoky black
• Black: 70% buckskin, 24% smoky black, 6% palomino
• Chestnut: 58% buckskin, 34% palomino, 8% smoky black
• Buckskin: 44% buckskin/perlino, 3% palomino/smoky black/cremello/smoky creme
• Palomino: 29% buckskin/perlino, 17% palomino/cremello, 4% smoky black/smoky creme
• Cremello: 58% cremello, 33% perlino, 8% smoky creme
• Perlino: 88% perlino, 6% cremello/smoky creme
• Smoky Black: 35% buckskin/perlino, 12% smoky black/smoky creme, 3% palomino/cremello
• Perlino: 88% perlino, 6% cremello/smoky creme

Grey is not a color but a modifier. Grey is an ongoing process of depigmentation of the color and slowly removes the pigment from the base color. If a grey stallion is heterozygous for grey (carries 1 grey gene) then there is a 50% chance of the foals being grey; if he is homozygous (carries 2 grey genes) then every foal sired will be grey. All horses with the grey modifier will end up varying from grey to white.
