Brown eyes are dominant to blue eyes. A purebred brown eyed person has children with a blue eyed person. What are the genotypic and phenotypic ratios of their offspring?

In cats, the allele for short hair is dominant to long hair. If a heterozygous short haired cat mates with a long haired cat, what will the genotypic and phenotypic ratios of the offspring be?

In flowers, blue is incompletely dominant to yellow. If a homozygous blue flower is crossed with a homozygous yellow flower, what will the genotypic and phenotypic ratios of the offspring be?

In mice, coat color is controlled by a gene with the dominant allele (B) for black and the recessive allele (b) for brown. A black female is crossed with a brown male and produce a litter of 10 black and 2 brown mice.
What are the genotypes of the parents?
What is the expected phenotypic ratio of the babies?
