When crossing a black normal-haired rabbit with a white short-haired male in F1, all rabbits are black normal-haired

When crossing a black normal-haired rabbit with a white short-haired male in F1, all rabbits are black normal-haired, and in F2, splitting is observed: 31 black normal-haired, 9 blue normal-haired, 13 white normal-haired, 8 black short-haired, 3 blue short-haired and 4-haired white rabbits. Determine: 1) how the color and length of the coat is inherited; 2) what are the genotypes of the parent individuals.

1) At the heart of the inheritance of the length of the coat is independent inheritance, the color of the coat is the complementary interaction of genes;
2) if the genes that control the color of the cocoon are designated as A and B, and the gene that controls the hair length is C, then the genotypes P: (women) AABBCC, (man) aabbcc.
