How many alleles does a baby guinea pig inherit from the mother?

The amount of alleles that a baby Guinea pig inherit from the mother are two, 1 from its mother and 1 from its father (The very reason why we use them as an experiment tester is because this similarities)

For Example, if its mother hat a dominant black fur (BB) and its father has recessive grey fur (bb), there is 100% chance that the baby will has a Bb genotype, which will give them either black fur or dark grey fur.
