In rabbits, long hair and black fur are produced by the dominant alleles L and B, which assort independently. The genotype ll produces short hair and the genotype bb produces white fur.
 
  A cross between a male with short, black fur and a female with long, white fur produces four offspring with short, black fur, four offspring with long, white fur, four offspring with short, white fur, and four offspring with long, black fur. What are the genotypes of the parents? A) llBB  LLbb
  B) LlBb  LlBb
  C) llBb  Llbb
  D) LLBB  llbb
  E) Impossible to determine from the information given.
