The phenotype of the black guinea pig is black, and the pheno type of the white guinea pig is white.
4 offsprings
Assuming black allele exhibits complete dominance and the white allele is recessive, the genotype is Bb.

Depending on the genetics of the two black parents they could produce white offspring...or a number of other potential colors. The color genetics of guinea pigs is rather complex with multiple genes at several sites and there are no true albinos, however the ch allele controls the production of body color and results in white with colored points and full white individuals with pink eyes. The cr allele produces ruby eyed/dark eyed whites.
If we assume "S" is the short haired trait, it could be 1 of 2 things. The first is "Ss". The pig still carries the long hair recessive gene, but it is not shown in the phenotype. The second is "SS". The pig does not carry the long hair gene and will probably not pass it onto the offspring. The second possibility is most likely going to happen with a purebred, but the guinea pig could still have gotten a recessive "s" from a parent - short haired or not.

A single coloured guinea pig is called a self. (a guinea pig that is all black, white brown,etc)

Well. I had a black guinea pig that had a white baby. It depends on her genetics. Their will probably be at least one white but no one knows exactly what the babies will look like.
guinea pigs can come in many colors, white, black, brown, orange, or mixed.
Cross between homozygous black rough (BBRR) guinea pig and homozgous white smooth guinea pig (bbrr) produced black and rough animals in F1 generation.
your guinea pig may be a hybrid (not a purebred), this means it would be part white crested part other guinea pig breed. this would explain why the guinea pigs fur has white.
Petri, a peanut butter colored guinea pig,Smorez, a black,white and peanut butter brown guinea pig,and Shadow, a black labradoodle. Note: These are from 2009 only

It's not any sort of problem. It could just be genetics, was his mom/dad a black guinea pig? Also, it could just be a whisker because my piggy is red and gray and she has some black and white whiskers.
