Question

in garden peas tall plants dominate short plants. which of the following punnett squares most accurately represents an individual that is heterozygous tall crossed with a short individual?
1
2
3
none of the choices are accurate
the punnett square labeled 3
the punnett square labeled 2
the punnett square labeled 1

Explanation:

Step1: Determine Genotypes

Heterozygous tall: \( Tt \) (produces gametes \( T \) and \( t \)). Short individual: \( tt \) (produces gametes \( t \) and \( t \)).

Step2: Analyze Punnett Squares

• Square 1: Top gametes \( T, t \); Side gamete \( t \). Crosses: \( Tt, tt \) (matches \( Tt \times tt \)).
• Square 2: Top gamete \( T \); Side gametes \( T, t \). Crosses: \( TT, Tt \) (not \( Tt \times tt \)).
• Square 3: Top gametes \( T, t \); Side gametes \( T, t \). Crosses: \( TT, Tt, Tt, tt \) (matches \( Tt \times Tt \), not \( Tt \times tt \)).

Answer:

the punnett square labeled 1
