Cavalier Coat-Color Inheritance

The four Cavalier coat colours:

   
Blenheim: is a combination of a red coat ee and a parti-colour pattern spsp. Our Blenheim puppy can only ever have the gene combination atateespsp. He has to have two genes for red and two for piebald/parti-colour, as explained above - so no other options are possible.
   
Ruby: is a combination of a red coat ee and a solid colour pattern - which can be either SS or Ssp. So a Ruby puppy can come in two flavours, depending on which combination of solid colour pattern genes he receives: so he can be either atateeSsp or atateeSS, but he will look exactly the same!
   
Tricolour: is a combination of a black coat, which can be either EE or Ee, and a piebald/parti-colour pattern gene spsp. So a tricolour puppy also comes in two flavours, this time depending on the combination of the black coat colour genes that he receives: he can be either atatEEspsp or atatEespsp but he also will look exactly the same!
   
Black and Tan: is a combination of black coat colour and solid colour pattern genes. Our Black and Tan puppy has the most complicated gene combination options: because he has dominant (strong) genes for both coat colour and pattern he can come in four different flavours! His black coat can come from either the pair of genes EE or Ee, and his solid coat pattern genes can be either SS or Ssp. So this complex little pup can be atatEESS, atatEESsp, atatEeSS or atatEeSsp. you will not be able to tell from his coat which combination of genes he has received
