For a certain breed of cat, short tails are dominant (T) and long tails are

recessive (t). The Punnett square below shows a cross between two parents.

What is the phenotype ratio for this cross?

A. 2 long, 2 short

B. 1 long, 3 short

C. 3 long, 1 short

D. 4 long, o short

There is no "Punnett square below" could you tell me the genotypes of the parent cats so I can esaily answer your question.

The doiminant trait's phenotype is expressed when there are two copies of same dominant allele (TT) OR when there is a pair of allele in which one allele is dominant and the other one is recessive (Tt). For a recessive phenotype to occur the two allele must be of recessive traits (tt).

Thus the phenotype of allele pairs in the punnet square are as follows -

TT - Cat with long tails

Tt - Cat with long tails

tt - Cat with short tails

Thus the phenotype ration of cat with long tails to cat with short tails is

Therefore, the answer is C.) 3 long, 1 short
