Question

A black coat is dominant over brown coats in guinea pigs. Cross two heterozygous guinea pigs to see

the possibilities of their offspring

For the answer to the question above, the black coat allele will be represented as the capital letter over the lowercase letter in guinea pigs. When crossing, you get 25% for homozygous dominant, 50% for heterozygous dominant, and 25% for homozygous recessive.
