OK so I've done them..Whanna see?

As you can see the follicle is very slightly colored. The light pigment darkens along the shaft and with some hairs quite dark.

hoofpick Thu, 06/23/2011 - 22:04

And YES the pigment is loading to one side (as a dun horse does) in more than half the hairs..!! The tips also clear.

hoofpick Thu, 06/23/2011 - 22:30

Well here is Tequila..a blue..
Um what does this mean?? "The selected file 100_3803.JPG could not be uploaded. The file is 1.36 MB which would exceed your disk quota of 50 MB".

Thank you!
Ok a blue...Clear follicles and is clear for at least a 1/3 of the shaft ( you can see also with the naked eye that it is clear near the follicle then "colors"

OMGosh that is the coolest thing ever! What can we conclude then from these? Tequila's hair looks quite interesting with the spots of color & voids. Shouldn't we have this thread on the canine side as well for a point of interest over there? :D

hoofpick Fri, 06/24/2011 - 17:26

Just in quickly as I've got to go and give lessons but yes it needs to be moved. I'll be back to explain the pics. :)

ok, If the first one (50 cents) was a horse I would have to say it was a bay or darkish red dun... BUT... the follicle is slightly pigmented so that would usually indicate no dilution. Even a black dun-nearly impossible to tell other than looking under the microscope, has a clear follicle and tip.
Now the second dog-the blue one ..to the naked eye is colorless from the follicle to about 1/3 of the way towards to the tip. Then starts to show the ovoids-the big blob things and the pigment going goldish tan. Also the pigment seems to "bleed" from the ovoids and also stays closer to the medulla. I have yet to see this so extream in horse color. The tip contains pigment of sorts in a "strand" form.
So in saying all of this I cannot tell you if there is any "dilution" as I need a "proven" dilute to compare with.
Bloody interesting though!!!

rodeoratdogs Mon, 06/27/2011 - 13:54

That is interesting! But I thought that the blue was already known to be a dilution and the choc was the one that was debatable?? :-?

Daylene Alford Mon, 06/27/2011 - 18:56

Yes, blue is a dilution. In fact, it is on the Dilution locus (D). Brown is the one we were having the discussion about a while back.

rodeoratdogs Mon, 06/27/2011 - 19:04

Yes and we were trying to decide if the brown was a dilution or a modifier....right Daylene? :D Did you see our discussion on the canine side hoofpick?

Oh you took the words right out of my mouth Daylene lol, I just popped over to the canine side to post the link to the brown discussion to post it here for hoofpick and you posted.

Ok so the lady that bought the pearl puppy from me said she was sorry she hadn't sent me the hairs yet but she still plans to. I hope she does and I will forward them to hoofpick :D. So in theory should the pearl (diluted choc) hairs look the same as the blue hairs and have the same ovoids as the blue hairs but just a different color????

Daylene Alford Mon, 06/27/2011 - 19:51

Yes, they should.

If everyone remembers that blue cats I sent had the ovoids also which is too cool.

hoofpick Thu, 06/30/2011 - 20:07

Well if it was a horse (the brown) I'd have to say it more than likely would be but the slight coloring of the follicle is throwing me.

Daylene Alford Thu, 06/30/2011 - 20:37

According to horsegen, mutations in TYRP1 (this is where brown is found) are considered modifiers not dilutions. The reason is that it isn't though to affect the distribution or amount of pigment but rather alters the pigment so that it reflects light differently thus altering the color. She also stated that technically a dilution reduces the amount of pigment but that it can be very difficult to distinguish between a dilution and a modifier even with modern equipment because it is so difficult to measure how much pigment is really present. Since she has a phd in genetics I'll just take her word for it. :bounce

Got pearl dog hairs in the mail today :bounce ! If I send those to you hoofpick will you take pictures of those too so we can see if they have similar ovoids like the blue? Pearl is diluted Chocolate.

hoofpick Sat, 07/09/2011 - 18:43

Ooh yes please!!! Yes Horsegen was the person who encouraged me to do the microscope stuff.. Her knowledge and expertise is boundless!!! And that description is absolutely spot on!

rodeoratdogs Sat, 07/09/2011 - 19:39

Ok I'll get them off to you on monday. :D

the sample is from Kodiak a pearl/tan/white offspring of Tequila & 50 Cent.

This little guy although I'm sure he's much bigger now. He's Rodeo's litter mate.
