Question

for each offspring genotype in the punnett square you just completed, determine the phenotype. in other words, what is the predicted fur color and eye color of the offspring? using your punnett square from the last step, fill in the predicted fraction for each phenotype in the data table below

	black fur and black eyes	black fur and red eyes	white fur and black eyes	white fur and red eyes
predicted percentage	%	%	%	%

finally, convert the predicted fractions into predicted percentages.

Explanation:

Step1: Recall Fraction to Percentage Conversion

To convert a fraction to a percentage, multiply the fraction by 100. The formula is: $\text{Percentage} = \text{Fraction} \times 100$.

Step2: Calculate for Black Fur and Black Eyes

Given the fraction is $\frac{9}{16}$.
$\text{Percentage} = \frac{9}{16} \times 100 = \frac{900}{16} = 56.25\%$.

Step3: Calculate for Black Fur and Red Eyes

Given the fraction is $\frac{3}{16}$.
$\text{Percentage} = \frac{3}{16} \times 100 = \frac{300}{16} = 18.75\%$.

Step4: Calculate for White Fur and Black Eyes

Assuming the fraction is $\frac{3}{16}$ (since the Punnett square for dihybrid cross with heterozygous parents usually has 9:3:3:1 ratio).
$\text{Percentage} = \frac{3}{16} \times 100 = \frac{300}{16} = 18.75\%$.

Step5: Calculate for White Fur and Red Eyes

Assuming the fraction is $\frac{1}{16}$.
$\text{Percentage} = \frac{1}{16} \times 100 = \frac{100}{16} = 6.25\%$.

Answer:

• Black Fur and Black Eyes: $56.25\%$
• Black Fur and Red Eyes: $18.75\%$
• White Fur and Black Eyes: $18.75\%$
• White Fur and Red Eyes: $6.25\%$
