Question

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

Explanation:

Step1: Recall Heterozygous Cross

A heterozygous individual for tall/short (Tt) crossed with another Tt. The Punnett square should have both parents contributing T and t alleles. So the top row (parent 1) and left column (parent 2) should be T and t.

Step2: Analyze Each Square

• Square 1: Left column is t, top row T and t. One parent is tt (homozygous recessive), not heterozygous cross.
• Square 2: Left column T and t, top row T. One parent is TT (homozygous dominant), not heterozygous cross.
• Square 3: Top row T and t (parent 1: Tt), left column T and t (parent 2: Tt). Correctly represents Tt × Tt.

Answer:

the punnett square labeled 3
