Yep esp if you add another 'Roaning' pattern lol
Since it's been said that GG tend to keep the darker manes & tails for much longer (some well into their 20s o.O ) I'm thinking & hoping she's Gg since her mane & tail have quickly gone 'pale' - suppose she'll either prove or disprove it when her tests come back ;)

GGs tend to go gray faster than Ggs. Not the other way around usually.

Lol - I suppose it depends on who you talk to ;)
Person I spoke with has bred Andys for 60 odd yrs & swears by the colour of manes & tails- GG for darker, Gg for lighter...we shall soon see ;)
Unless her sire was also a Grey ontop of chestnut roan she will test Gg- I only saw him once, on the hills with his band, so couldnt tell if he was graying or not- he was only 3yrs old then & was sold 2yrs later so I never knew if he went 'white'or not :)
The research article
The research article published on the grey mutation is where it was published that GG goes grey faster than Gg. Statistically homozygotes will grey faster and heterozygotes are more likely to develop flea-bites. This was based on extensive analysis of hundreds of grey horses.

Well in this case she's proven them wrong & the Andy breeder right, because her results came in both as heterozygous Gray & Roan (Gg/Rr), so I'm wrapped :grin: .
Havent tested her for any other colours as I know she carries Red & her Dam was either Dk Bay or Seal Brown & Nex is Seal Brown, I dont care if she's able to throw black or not- I much rather Seal Brown lol.
Havent tested her for any patterns as there hasnt been broken coloured horses in this line either at all or for many, many generations (aside from the white leg marking/s or face marking they've mostly been plain solid colours)...do you think it worth testing her from Frame to be on the safe side when I test my Pinto or considering her background would that just be a waste of money that I could use to get another test done on my pinto.

Pretty!!!!
I know what you mean- I didnt really care other than I wanted/ hoped for her to be Gg rather than GG as it gives me more colour options... like getting a foal that wont Gray out lol ;p

I only said she proved them wrong, not that it was incorrect - personally I dont care one way or the other- it was just a tit bit of info which proved correct in this case & I got the result I was hoping for :grin: Although RR would have been better ;)
Thank you. We breed about
Thank you. :) We breed about 25-30 foals a year and I've seen both ends of the spectrum when it comes to grey theories. ACC saw on the FB group the other day, someone suggested that reds grey faster then blacks yet about half of our foals (all black based) grey almost completely by 2 (some are GG and some are Gg)... Then there's the argument about how the greying process is affected by homo or hetero and I've seen both ways... So I can't really bring myself to feel one is more correct then the other. =\ Unless I just have a ranch full of rebels... lol
In general graying rates are
In general graying rates are polygenic. So statistically reds and homozygous grays may gray faster. If overall numbers show that, there is likely something to it. Red pigment has shown a tendency of being more easily diluted and more readily allows white markings to express than it's black pigment counterpart. So other research does point to this hypothesis as being likely.
Another thing to keep in mind is there are other genes that don't visibly express that may suppress or boost graying. Environment may also influence graying rates. Looking at the overall trends from a statistically large number of horses gives better insight to what influences what than just looking at a small handful. The Comicos likely have an uncommon suppressor causing their unusually slow graying. In any polygenic trait it's a mixed bag of genetics and environment but statistics give us a better idea.
That is very interesting! It
That is very interesting! It is always fun to see the greying process.
