probability in genetics can be expressed in fraction, percentages, or
use the punnett square to complete the table in the column to the right.

Explanation:

To solve this, we analyze the Punnett square (assuming a typical 2x2 grid with 4 cells, 1 shaded as an example for the first case):

First Punnett Square (1 shaded cell):

Step 1: Determine Fraction

Total cells = 4, Shaded cells = 1. So fraction = $\frac{1}{4}$.

Step 2: Convert to Percentage

Percentage = $\frac{1}{4} \times 100 = 25\%$.

Step 3: Determine Ratio (Shaded:Unshaded)

Unshaded cells = 4 - 1 = 3. Ratio = $1:3$.

Second Punnett Square (assuming 2 shaded cells, common in monohybrid crosses):

Step 1: Determine Fraction

Total cells = 4, Shaded cells = 2. Fraction = $\frac{2}{4} = \frac{1}{2}$.

Step 2: Convert to Percentage

Percentage = $\frac{1}{2} \times 100 = 50\%$.

Step 3: Determine Ratio (Shaded:Unshaded)

Unshaded cells = 4 - 2 = 2. Ratio = $1:1$.

Filling the Table (First Case):

COLOR	Fraction	Percentage
Unshaded	$\frac{3}{4}$	$75\%$

Ratio: $1:3$

Filling the Table (Second Case):

COLOR	Fraction	Percentage
Unshaded	$\frac{1}{2}$	$50\%$

Ratio: $1:1$

(Note: The exact numbers depend on the actual shading in the Punnett square. Adjust fractions/percentage/ratio based on the number of shaded cells.)

Final Answers (Example for 1 shaded cell):

• Fraction (Shaded): $\boldsymbol{\frac{1}{4}}$, Percentage: $\boldsymbol{25\%}$, Ratio: $\boldsymbol{1:3}$
• Fraction (Unshaded): $\boldsymbol{\frac{3}{4}}$, Percentage: $\boldsymbol{75\%}$

(For 2 shaded cells, adjust to $\frac{1}{2}$, $50\%$, and $1:1$ as shown.)
