Answer:

See the answer below

Explanation:

Normal height - H

Short height - h

Heterozygous - Hh

A cross involving heterozygotes would be Hh x Hh

         Hh    x    Hh

      HH   Hh   Hh   hh

Since H is dominant over h;

HH and Hh would produce normal height phenotypes.

hh will produce a short height phenotype.

Thus;

Probability of normal height phenotype resulting from the cross = 3/4 or 75%

Probability of short height phenotype resulting from the cross = 1/4 or 25%
