NOTE: This HancockHorses.com project is intended for reference not for advertisement. This is a free service, so the work of submission falls upon the stallion owner. If you have or know of a 100% roan producing (Hancock) Quarter Horse stallion not included on this webpage, you are welcome to email a submission for listing on this page - be sure to include photo and all stallion information - see above for what we want - I do not have time to go visit and search your website for your location, year of birth of your stallion, his AQHA# etc etc. Until I receive it all, I prefer not post any of it, so that I don't have to post several times for one horse. I also do not often have time to respond to you pointing out what else I still have not received yet, or re-copy these instructions to you personally via email - so if your horse qualifies and you have submitted him, and i have not posted him in a timely manner, assume you missed something. Please resend, making sure all info shown in above listings are included. THANK YOU for your understanding!! That will make my job so much easier! :o)

now that the roan homozygosity test is available...
you can test your stallion w/ UC DAVIS: Genetic Roan Zygosity Test

The Roan Zygosity test is not a direct test for the Roan gene.
The analysis is based on markers associated with Classic Roan in
Belgian Draft Horses, Gypsy Cobs, Miniature Horses, Quarter Horses,
Tennessee Walking Horses and Welsh Ponies.
Note: There are horses with a roaned appearance that test negative for the Classic Roan gene.
The genetic basis for this pattern called roaning is not known at this time.

LEGEND of applicable equine genetic color codes:
(to be approved by geneticists, but works for our purposes here so far)

E - RED FACTOR
EE - black, homozygous
Ee - black, heterozygous
ee - chestnut/sorrel
E_ - phenotypically black, red gene unknown (progeny records incomplete or unknown to us)

A - AGOUTI on BLACK and RED HORSES see details here (will be moving soon to curlyhorses.com)

Rn - CLASSIC ROAN
Rn/Rn - roan, homozygous
Rn/N - roan, heterozygous (if one foal produced is non-roan, the roan parent is considered Rn)
N/N - markers inconsistent with horse being roan

CH - CHAMPAGNE
Ch/Ch - Two copies of the altered sequence detected. All offspring are expected to be Champagne diluted.
Ch/N - One copy of the altered sequence detected. Chestnut color (red) is diluted to gold, bay to tan with brown points and black to darker tan with brown points.
N/N - No evidence of altered sequence detected.

Cr - CREAM (CREME)
Cr/Cr - homozygous creme gene (cremello [sorrel] or perlino [black or bay])
          (2 copies of creme gene bleaches out both red and black hair)
Cr/N - heterozygous creme gene (palomino [sorrel], buckskin [bay] or smoky black)
          (one copy of creme gene dilutes only red hair)
N/N- does not carry creme gene (therefore would not be listed in a horse's genetic color code)

D - DUN
D/D - homozygous dun (no genetic test avail for this yet) (dun, grulla, red dun- affects red hair only)
D/N - heterozygous dun (dun, grulla, red dun - affects red hair only)
N/N - does not carry dun gene (would not be listed)

G - GRAY (GREY)
G/G - Two copies of the grey gene. Horse will turn gray and all offspring will be grey.
G/N - One copy of the grey gene. Horse will turn grey and approximately 50% of offspring will be grey.
N/N - No copies of the grey gene. Horse will not turn grey.

O - OVERO (LETHAL WHITE OVERO)
O/O - Only the altered sequence in the EDNRB gene detected. This result has only been obtained with samples from lethal white overo foals.
O/N - One copy of the altered sequence detected. If bred to another N/O horse, there is a 25% chance of producing a lethal white overo foal. The N/O type has been detected in Paints (including breeding stock), Pintos, Thoroughbreds, Miniatures, Quarter Horses and Tennessee Walking Horses.
N/N - No evidence for the altered sequence detected.

Prl - PEARL
Prl/Prl - Two copies of the altered sequence detected.
On a chestnut base color, a uniform apricot color of body hair, mane and tail will result.
Prl/N - One copy of the altered sequence detected.
If Cream dilution is also present, a pseudo-double Cream dilute phenotype will result.
N/N - No evidence of the altered sequence detected.

S - SABINO 1
SB1/SB1 - Two copies of the Sabino 1 gene detected. Complete or nearly complete white phenotype expected.
SB1/N - One copy of the Sabino 1 gene detected. Horse typically may have 2 or more white legs, blaze, spots or roaning in the midsection and jagged margins around white areas.
N/N - No evidence of altered sequence detected.

TO - TOBIANO
TO/TO - Two copies of altered sequence. Horse is homozygous for Tobiano. All offspring will inherit Tobiano.
TO/N - One copy of altered sequence. Approximately 50% of the offspring will inherit Tobiano.
N/N - No evidence of altered sequence detected. Horse is not Tobiano.

Z - SILVER
Z/Z - Two copies of altered sequence detected. Black-based horses will be chocolate with flaxen or lightened mane and tail. Bay-based horses will have lightened black pigment on lower legs, mane and tail. No effect on chestnut color.
Z/N - One copy of the altered sequence detected. Black-based horses will be chocolate with flaxen or lightened mane and tail. Bay-based horses will have lightened black pigment on lower legs, mane and tail. No effect on chestnut color.
N/N - No evidence of the altered sequence detected.
