Breeding Records - Color Genetics Since Tee J Iceman is a
young stud and we wanted to know what to expect him to produce, we had
the following test done on him. I am
going to be adding a lot of information to this site about color
genetics in the next few months, but for now I want to list what Tee J
Iceman's color genetics are so you can try and determine what
color foals you may get.
Red Factor - ee
This was easy to determine as he is a Red
Dun/Palomino. Tee J will only sire a Bay/Black/Buckskin, etc. if
the mare is black based. She would have to be "Ee" or "EE".
If she is "EE" then even if bred to Tee J you still wouldn't get a red
based foal. If you bred and "Ee" mare you could get any color.
Tee J would contribute an "e" but the mare could contribute either "e"
or "E". An "ee" foal would be red based, and "Ee" foal would
be black based.
Agouti - Aa
This was determined by laboratory testing. The Agouti is what distributes
the black pigments to the points (bays and buckskin) or in the absence
of the Agouti then the horse is black or Smokey Black (if it possesses
the creme gene). Since Tee J is a Red Dun/Palomino it is
impossible to know without testing or siring many foals, as the Agouti
does not effect a red based horse. Tee J is heterozygous for Agouti not
Homozygous. An "AA" horse would always throw a Bay or Buckskin (if
the base coat was black not red, Agouti does not effect Red horses) not
Black. So if you have a red (Palomino or Chestnut/Sorrel) mare you
won't know what she has unless you have had her tested or she has
produced a
lot of foals.
Creme - nCr
Tee J possess a single dilute gene.
He was tested on Nov. 23, 2007.
Dun -
Tee J is also a Red Dun,
determined by his strong dorsal stripe, leg barring, and red legs.
His mane and tail are white because he also carries the creme gene (see
above).
If you are unsure of what combination of
genes your mare may have, feel free to call me and maybe we can
determine it from her pedigree and any foals she may have already had.
If you would like more information, or would like to have your mare
tested, following are two Genetics Labs:
