how many of the four offspring will be short?
0% (0 out of 4)
50% (2 out of 4)
75% (3 out of 4)
100% (4 out of 4)

Explanation:

Step1: Determine the dominant and recessive traits

Assume \( T \) is the dominant allele (for tall) and \( t \) is the recessive allele (for short). Short plants have the genotype \( tt \).

Step2: Analyze the offspring genotypes

From the Punnett - square, the offspring genotypes are \( Tt, Tt, Tt, Tt \). There are no \( tt \) genotypes.

Answer:

A. 0% (0 out of 4)
