In clown fish, the allele B for blue scales is dominant over the allele b for yellow scales. On another chromosome, the allele N for long tail fin is dominant over its allele n for short tail fin. Give the most probable genotypes for the parent cross when the following offspring are produced:

a) Parents: Offspring:
blue with long tail x yellow with short tail 56 blue with long tails, 53 yellow with long tails

b) Parents: Offspring:
yellow with long tail x blue with short tail all blue with long tails
