Question

Widow's peak is a dominant trait (W). Tongue-rolling is a dominant trait (T). Two people who are heterozygous for both traits (widow's peak, tong-roller) get married and have children. Complete the Punnett square to show the parents the probabilities for each child, then answer the question that follows. Which box has the genotype wwTT? A) 1 B) 3 C) 4 D) 2

Answer 1

The box with the genotype wwTT is in box number 4.

Step-by-step explanation:

To determine the probabilities for each child, we can create a Punnett square. Since both parents are heterozygous for widow's peak (Ww) and tongue-rolling (Tt), we will have a 4x4 Punnett square. The genotypes are as follows:

• Top row: WwTT, WwTt, WwTt, Wwtt
• Second row: WwTT, WwTt, WwTt, Wwtt
• Third row: WwTT, WwTt, WwTt, Wwtt
• Bottom row: WwTT, WwTt, WwTt, Wwtt

The box with the genotype wwTT is in box number C) 4.
