I'm hoping this is allowed because even though the horses are fictional, I'm trying to figure out realistic genotypes for them.
Okay, so the pictures are of four "Tennessee Walkers" which is Red Dead Redemption 2's in-game version of the Tenessee Walking Horse breed. I *think* I've worked out the likely genetics for each horse below, which I'm trying to do in order to determine what their foals would potentially look like. None of the horses are related, or at least have any canon reason to be more related than any other given Tennessee Walkers.
The color descriptions in quotes are from the game; none of the horse names are canon except for Branwen.
- Bedivere (stallion)
"Mahogany Bay" but essentially seal brown, right?
E/e or E/E with A/A or A/a
heterozygous for sabino
- Rhiannon (mare)
"Black Rabicano"
E/e or E/E with a/a
homozygous recessive for rabicano/white ticking
- Branwen (stallion)
"Flaxen Roan"
e/e with Rn/Rn or Rn/rn
homozygous recessive for flaxen, but Wikipedia says it may be polygenic?
- Posy (mare)
"Red Roan" aka chestnut or strawberry roan
e/e with Rn/Rn or Rn/rn
heterozygous for sabino and/or splash
