What will be the phenotypic ratio of the f2 generation

In rabbits, black hair is due to a dominant gene; brown is recessive allele. Short hair is due to a different dominant gene carried at a location o a different chromesome. Long hair is recessive to short hair. In a cross between black and long hair individual homoxtgous for both traits and a brown shorthaired individual homoztgous for both traits, what will be the genotypic and pheno thypic ratio of the F1 generation? What will be the phenotypic ratio of the F2 generation?
