THE ROAN GENE IN COCKERS
|The R gene - The R gene
is known as roan.
It is a simple dominant
which means either you have it or you don't.
You can only get roan puppies if one parent is
The roan gene is expressed (seen)only in the
white areas of spotted dogs
(in our experience).
The roan genes works like this:
R - dominate to r, produces roan
r - recessive to R,meaning if you don't have it
you can't produce it .
Roan and Merle inheritance
ROAN DOES NOT SPONTANEOUSLY
COME FROM A BREEDING OF TWO NON ROAN PARENTS
There seems to be a very wide spread misconception
about the inheritance of roan as to whether it grades in to the ticking
The concept is being fostered by experts that
either do not breed cockers and are quoting other experts (who usually
are quoting other experts) or by breeders passing heavily ticked cockers
off as roan.
There is some evidence of roan being visible
on a solid colored cocker
when it is homozygous( R R ) .
If you want to see that the roan gene has nothing
to do with the ticking gene look at PROGRESSION
OF ROAN it is a documentation in pictures of a roan cocker that has
no ticking or anything that resembles ticking!!!!
