Explanation:

Step1: Analyze the Punnett square

In genetics, usually, the dominant allele (let's assume \(T\) is dominant for tall) and recessive allele (\(t\) for short). The genotype \(tt\) represents short.

Step2: Count the \(tt\) genotypes

Looking at the Punnett square, there are 2 boxes with \(tt\) genotype.

Answer:

2 out of 4
