If you are attempting to breed all white cockers
one of the ways to accomplish this would be to mate parents both carrying
the extreme spotting gene ( xsp ) but be aware of the fact that in some
breeds this can lead to occasional deafness !
I have seen a few pretty silly comments on the web about coat color
inheritance such as you can't be sure of anything concerning genetics ?
And that breeding two spotted cockers together will
sometimes produce solid puppies !!! I have a colloquialism for just
such a statement "There must have been a stranger in the wood pile"
In order to predict the color of puppies you must
know the color genes of the parents
Sometimes the only way to figure this is to know
the colors of the grandparents and or colors of previous puppies
( S=solid
dominant to=sp =spotted
and xsp=extreme spotted
)
( sp=spotted
dominant to xsp=extreme spotted
)
The first thing to remember in this series is
that when breeding a solid dog (S S) to a spotted dog whether it is the
normal spotting gene (sp) or the extreme spotting gene (xsp) there is a
very good chance of getting mismarked puppies ( this can occur the first
cross to solid or in succeeding generations ) So in the charts below
I have listed all those with the possibility of being mismarked as such
to help in the differentiation !
A dog that is"S S"is solid
A dog that is"S sp"is mismarked
A dog that is"S xsp" is mismarked
A dog that is"sp sp"is spotted
A dog that is"sp xsp"is spotted
A dog that is"xsp xsp"is extreme spotted
