Question

Two short-tailed cats are bred together. They produce three kittens with long tails, five short tails, and two without any tails. a. From these results, how is tail length in these cats inherited? b. Write out the genotypes paired with the matching phenotypes for the offspring to support your answer.

Answer 1

a) Cats show incomplete dominance which means the kitten can be born with full length tails, short length tails and without tails.

b) The genotype of the parent will be heterozygous (Tt ) and the kittens will be:

Genotype | Fenotype

-TT | (long tail)

-Tt | (short tail)

-tt | (no tail).
