Breeding Poodles for Color
Determine the phenotypes of the potential poodle sires and dams. A phenotype is the physical representation of the genotype, or the DNA "blueprint" determining the poodle's color. The standard poodle colors accepted by the AKC are black, blue, cafe-au-lait, brown, apricot, cream and white. Each color has a specific genotype that, when present, determines a poodle's color.
Determine the nose colors of your breedstock. A poodle's nose may be the same color as the coat, or it could be different. The poodle's nose color could greatly assist you in determining the dog's genotype.
Understand the basic poodle allele loci. This is necessary when determining possible poodle coat and nose colors. It is the interplay between the two alleles that allow such variation in poodle color, and even variation within a color. The "E" locus returns a phaeomelanin, or "brown" pigment. However, it can represent black or brown coloring, depending on whether it is "E" or "e," with the capitalized being the dominant black, and the lowercase, the recessive brown. A poodle with "EE" or "Ee" will therefore always be black, whereas "ee" will be brown. Similarly, the "B" locus contributes to red coats, the "G" contributes to silver coats, and the "D," a dilution. This last dilution locus, when paired with another locus, dilutes the color represented by its paired allele. An example is genotype "Eedd," which would appear as a diluted black poodle, referred to as "blue."
Use the E, B, and D loci to determine the possible coat and nose genotypes of your breedstock. For example, a black poodle with a black nose could have a genotype of EEBB, EeBB, EeBb or EEBb. The first two letters symbolize the coat color, and the second two, the nose color. When capitalized, the allele is dominant. Because black is the dominant color amongst all poodles, anything pared with "E" will be black. In the above example, no black poodle possesses a brown nose, thus a genotype of EEbb or Eebb cannot occur.
Mix and match your possible mates to get a rough prediction of what colors the possible litters will produce, once you've identified your sires and dams' possible genotypes. This is highly inaccurate, but not impossible. For example, breeding a brown sire with genotype "eebb" to a black dam of genotype "EeBb" will return puppies with possible coat genotype combinations Ee and ee -- some black, some brown. Similarly, the nose colors can be Bb or bb, with some black and some brown, though all black poodles will have nose genotypes Bb (black noses).
