Question

For a certain breed of cat, short tails are dominant (7) and long tails are

recessive (7). The Punnett square below shows a cross between two parents.
What is the phenotype ratio for this cross?

A. 4 long, 0 short
B. 3 long, 1 short
C. 2 long, 2 short
D. O long, 4 short

Answer 1

The phenotype ratio for this cross is 2 long tails to 2 short tails.

Step-by-step explanation:

The Punnett square provided shows a cross between two parents with the genotypes:

TTtTt tt

In this cross, short tails (T) are dominant and long tails (t) are recessive. From the Punnett square, we can determine the phenotypes of the offspring. There are 4 possible genotypes in the offspring: TT, Tt, Tt, tt. This results in a phenotype ratio of 2 short tails to 2 long tails, or C. 2 long, 2 short
