Question

based on this punnett square, what is phenotypic probability of the plant being tall? t t t tt tt t tt tt

Explanation:

Step1: Identify Genotypes

The Punnett Square has four cells: \( TT \), \( Tt \), \( Tt \), \( tt \).

Step2: Determine Tall Phenotype

Assume \( T \) is dominant (tall), so \( TT \) and \( Tt \) show tall phenotype. Count tall - genotype cells: 3 ( \( TT \), \( Tt \), \( Tt \) ). Total cells: 4.

Step3: Calculate Probability

Probability = \(\frac{\text{Number of tall - phenotype cells}}{\text{Total cells}}=\frac{3}{4}\) or \( 75\% \).

Answer:

\(\frac{3}{4}\) (or \( 75\% \))
