The complete question is as follows:

Two short-tailed (Manx) cats are bred together. They produce three kittens with long tails, five short tails, and two without any tails. From these result, how do you think tail length I'm these cats are inherited? Show the genotypes for both the parents and the offspring to support your answer.

Answer: Incomplete dominance

Explanation:

The incomplete dominance is a kind of intermediate inheritance in this one allele responsible for the expression of a particular trait is not completely expressed. As a result of this an intermediate phenotype get expressed in the physical trait, which is a combination of the phenotypes of both type of alleles.

Manx cat is indicating towards the incomplete dominance in this the kitten can be born with the full length, short length tails or even without the tails.

If the genotype of the parent is heterozygous (Tt) then kittens are expected to have genotypes like TT (long tail) Tt (short tail) tt (no tail).

Thus the kitten can be short length, long tailed and they can be without tail.
