Explanation:

Step1: Define genotype terms

• RR: Homozygous dominant
• Rr: Heterozygous
• rr: Homozygous recessive

---

Step2: Solve first Punnett Square

Step2a: Identify parent alleles

Mother (RR): $R, R$; Father (rr): $r, r$

Step2b: Fill Punnett Square

$$\begin{array}{|c|c|} \hline Rr & Rr \\ \hline Rr & Rr \\ \hline \end{array}$$

Step2c: Calculate percentages

% RR = $0\%$
% Rr = $100\%$
% rr = $0\%$
% dominant = $100\%$ (all Rr show dominant trait)
% recessive = $0\%$

Step3: Solve second Punnett Square

Step3a: Identify parent alleles

Mother (Rr): $R, r$; Father (rr): $r, r$

Step3b: Fill Punnett Square

$$\begin{array}{|c|c|} \hline Rr & rr \\ \hline Rr & rr \\ \hline \end{array}$$

Step3c: Calculate percentages

% RR = $0\%$
% Rr = $50\%$
% rr = $50\%$
% dominant = $50\%$ (Rr shows dominant trait)
% recessive = $50\%$ (rr shows recessive trait)

Answer:

Genotype Vocabulary Table:

Genotype	Vocabulary word(s) to describe the genotype
Rr	Heterozygous
rr	Homozygous recessive

1. Cross homozygous dominant (RR) x homozygous recessive (rr)

Punnett Square:

$$\begin{array}{|c|c|} \hline Rr & Rr \\ \hline Rr & Rr \\ \hline \end{array}$$

• % RR = $0\%$
• % Rr = $100\%$
• % rr = $0\%$
• % dominant = $100\%$
• % recessive = $0\%$

---

2. Cross heterozygous (Rr) x homozygous recessive (rr)

Punnett Square:

$$\begin{array}{|c|c|} \hline Rr & rr \\ \hline Rr & rr \\ \hline \end{array}$$

• % RR = $0\%$
• % Rr = $50\%$
• % rr = $50\%$
• % dominant = $50\%$
• % recessive = $50\%$
