Bonjour,
Avez vous entendu parler de cela :
Rn/Rn - 2 copies of Classic Roan variant are present. All offspring will inherit Classic Roan.
Rn/N - 1 copy of Classic Roan variant is present. 50% of offspring will inherit Classic Roan.
Rn*/Rn* - 2 copies of an alternative Roan variant are present. All offspring will inherit the
alternative Roan variant.
Rn/Rn* - 1 copy of Classic Roan and 1 copy of an alternative Roan variant are present. All
offspring will inherit either Classic Roan or the alternative Roan variant.
Rn*/N - 1 copy of an alternative Roan variant is present.
N/N - No copies of Roan are present.
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.
Les seuls site qui parle du RN* ou des "taches magique" ou ronning sont eux:
