Biology homework help!?

In guinea pigs, black fur is controlled by a dominant gene, B. White fur is due to the recessive, b. what would be the result of crossing a black male that is zygous dominant with a white female that is zygous recessive? And also, what would be the result of a male and a female from the first generation of offspring to make a second generation. I also need the phenotype and genotype ratios for the offspring in each generation.
