Question

choose all that apply 9. 1 pts. if two tt parents are crossed (punnet square) the offspring... mark all that apply. a. there will be no tt b. 25% will be tt c. 50% will be tt d. 50% will be tt e. 25% will be tt flag this question for later review

Explanation:

Step1: Set up Punnett Square

Each Tt parent contributes T or t.

$$\begin{array}{c|cc} & T & t \\ \hline T & TT & Tt \\ t & Tt & tt \\ \end{array}$$

Step2: Calculate genotype percentages

Count each genotype:

• TT: 1 out of 4 = $\frac{1}{4} = 25\%$
• Tt: 2 out of 4 = $\frac{2}{4} = 50\%$
• tt: 1 out of 4 = $\frac{1}{4} = 25\%$

Step3: Match to options

Check which options align with results.

Answer:

B. 25% will be TT
C. 50% will be tt
D. 50% will be Tt
E. 25% will be tt
