Donkeys!

While adding pictures to the donkey gallery from a website I have permission from, I was getting quite puzzled on a family line of donkeys. I'm pretty sure I got it mostly figured out, but I thought it was still interesting how confusing it can be to figure out, even with good documentation of pedigree/progeny (plus good pictures). Theodora is the first, she is brown dun, by a "dark red" line and out of a "Gray, NLP" with a mixed grey and red background. So it would make since that she should be Ee,Aa, D_ heterozygous pangare. She has produced a grey dun by a black based ivory, a red dun by a red, and a brown dun by a solid black. http://www.merry-go-round-minis.com/Jennets/Theodora02a.jpg Her daughter Talleuah, is red dun, and fairly light at that with strong pangare, which it seems that red shows pangare a lot more strongly than black and black bases, same for horses I believe, at least in terms of white expression. Her sire was red based. http://www.merry-go-round-minis.com/Jennets/Talleulah022a.jpg Now the really interesting looking one is Eye Candy, daughter of Talleuah, while she looks almost like a dark sorrel, but with her sire being black, with an extensive black background, I figured the possibility of him being Ee was unlikely. So I figure she is brown, like her granddam, she is also heterozygous dun. She has produced a red dun foal by a red. http://www.merry-go-round-minis.com/4sale/Merry-Go-RoundsEyeCandyNew1a… If I find anything else sorta interesting in my tiredness, I'll post it here.

Actually zebras and horses are furthest apart from each other. Donkeys are the middleman so to speak. There goes that theory lol.

I found this zorse who is supposedly out of a roan mare. He is advertised as blue roan but I can't say I see it. I know classic roan is inheritable in mules. He is also interesting because he looks like an uber striped grullo. He is one I'd love to see tested for agouti. (scroll down to Zulu)

It would be neat to find out what makes donkeys more prone to skewing than their other equid relatives. It would also be interesting to see how many patterns are inheritable between the three zebra species (plains, mountain, Grevy's) since they all have different chromosome counts. Zebra crosses are interspecies hybrids in themselves, so a cross between a plains and a Grevy's zebra is the equivalent of a mule since they are both interspecies hybrids.

I need to look up more Grevy's and mountain zorses and zedonks since those crosses to plains zebras are most common.

Awesome CM! I really hope they reply to you. I also have to agree that is a really good point about Zulu possibly being very dark brown.

We already have the super dark brown horses so I don't see why we can't see that in zorses, we already see super light wild bay ones, so I don't see why we couldn't see the darker end. Of course it could really be black, but I still would want more evidence to support that (and that puts a huge hole in my theory).

I was thinking he was a pretty good example of when donkey skewing does NOT happen, LOL. Blows my mind when the Lp in a mule ends up with elongated 'bars' of colour rather than spots.
