color factors found here
'RECESSIVE BLACK' is the result of carrying the recessive black
agouti gene (a) in conjunction with the tan agouti gene. When a Cocker
Spaniel carries the 'a and at' the tan is not as well expressed.
A 'Recessive Black' is an all black cocker that carries a gene for tan
points (at) and recessive black( a). These individuals will sometimes eventually
show a small amount of tan on the eye brows ( sometimes only one eye )
or a few tan colored hairs under the tail. This change towards the tan
phenotype is occasionally permanent. All of these effected cockers will
pass on either tan point genes or recessive black to their offspring.
The recessive 'a' gene works similarly with the sable gene
Transitory Sable/recessive sable;
This is part of an email I sent in reply to a question about a transitory
A transitory sable is born with the base color only. Sable fades in
without the usual accompanying tan, last for a couple of days or a week,
then disappears. This phenomenon can occur a couple of times the first
year of life, never to return. This puppy's sire went through this transition
twice, first at a couple of months, sable started to show on the sides
of his head, lasted about a week. At six or eight months he began sabeling
over the top of his head, three days later it was completely gone. This
phenomenon is apparently (in my mind) the result of recessive black and
its affect on sable.
A tan pointed cocker carrying recessive 'a' will not express the tan
fully if at all, and can transition from a little to none.
A sable Cocker carrying recessive 'a' will only show sableing on the
parts of the body normaly not effected by tan points,.Eye lids not eyebrows,
outsides of ears not underneath, sides of the head not sides of the muzzle
