In Cocker Spaniels, black coat color (B ) is autosomal dominant over red coat color (b ) and solid color (H ) is autosomal dominant over spotted color (h) [either black-spotted or red-spotted on white].
A solid black male is mated with a solid red female. They produce a litter of six puppies: 2 solid black pups; 2 solid red pups; 1 black-spotted pup; and 1 red-spotted pup.
