Slick & Yo
Slick - Bar'O's Ogeechee of O'run - gold brindle and white parti - sire = pale fawn and white parti & dam = brindle and white parti - we can expect from this that Slick carries non-brindle and probably cch - since his sire is a pale fawn
Yo - Owrun Youghiougheny- blue brindle, Irish Marked, mask - sire = red fawn & dam = red brindle with white - we can expect from this that Yo carries non-brindle. Yo is a rather "blurred" brindle, which is probably an expression of "sabling" that is also seen in her one sabled fawn son.
Slick = AyAy(pure for fawn)
Slick is a rich, golden brindle - but his sire is a pale fawn, and Yo is not a pale, silver blue - so we will assume the following:
Slick = Ccch (pure for complete expression of red/yellow and blue pigments - carrying Chinchilla)
We already know the Yo is blue and Slick is not. 9 puppies is a statistically large enough sample to assume that Slick does not carry the gene, since there were no blue brindle or blue fawn puppies:
Slick = DD (pure for non-blue)
Slick does not have a mask and Yo does, so we know she has that gene to contribute.
Slick = EE (not masked)
Since Slick and Yo are both brindles the neither can have the dominant K gene that produces blacks. Neither parent is either dominant black or its blue dilution, both are brindle but since they produced non-brindle we know both are not pure for brindle.
Slick = kbrk (brindle, carrying non-brindle)
Since neither the parents nor any of the puppies are Roan we know the following:
Slick = rr (displays normal color and does not carry Roan)
We know from their appearance that Slick displays more white than does Yo, but the presence of the parti puppies shows that Yo carries that gene:
Slick = spsp(pure for parti)
Not enough data to tell.
All of this gives us the following analysis of the color genetics involved with these parents and their offspring:
Slick - Bar'O's Ogeechee of O'Run - gold brindle & white parti =AyAy Ccch DD EE kbrk rr spsp
Genetic notation is simply a "short-hand" method of conveying information about the genes carried and/or displayed. Dominant genes are noted as UPPERCASE and are listed first at each locus, when they are present. Recessive genes are noted as lower case and are listed second at each locus, when a dominant is present. In the case of 2 dominants or 2 recessives at the same locus the one that is dominant over it's locus partner is listed first. Superscript letters provide father description of the particular gene's actions. The above examples convey quick information about what colors these parents can be expected to produce:
Slick = AyAy Ccch DD EE kbrk rr spsp
AyAy - pure for red/fawn
Yo = AyAy CC dd EmE kbrk rr sisp
AyAy = pure for red/fawn
red and white, Irish Marked - AyAy CC or cch Dd EE kk rr sisp
All of Slick and Yo's puppies will carry blue, since Yo has no other gene to contribute at that locus. Also the Irish Marked puppies will carry parti - as Slick has no other gene to contribute at that locus. Any of the puppies could be carrying the Chinchilla (cch) but they do not express it as Yo does not have a matching recessive that would allow it expression.
