Let's break down the given information and fill in the blanks based on the results.
We start with the predicted fractions and percentages:
- For black fur and black eyes, the predicted fraction is [tex]\( \frac{9}{16} \)[/tex] and the predicted percentage is [tex]\( 56.25\% \)[/tex].
- The simulated fraction for black fur and black eyes is [tex]\( \frac{5}{10} = 0.5 \)[/tex], and the simulated percentage is [tex]\( 50\% \)[/tex].
We are also interested in the number of offspring with black fur and black eyes from 85 offspring.
### Explanation:
1. Predicted Fraction for Black Fur and Black Eyes:
- The predicted fraction for black fur and black eyes is [tex]\( \frac{9}{16} \)[/tex].
2. Predicted Percentage for Black Fur and Black Eyes:
- The predicted percentage for black fur and black eyes is [tex]\( 56.25\% \)[/tex].
3. Simulated Fraction for Black Fur and Black Eyes:
- The simulated fraction for black fur and black eyes in the experiment is [tex]\( \frac{5}{10} = 0.5 \)[/tex].
4. Simulated Percentage for Black Fur and Black Eyes:
- The simulated percentage for black fur and black eyes is [tex]\( 50\% \)[/tex].
5. Number of Offspring with Black Fur and Black Eyes:
- Out of 85 offspring, the number of offspring with black fur and black eyes can be found by multiplying the total number of offspring by the simulated fraction:
- [tex]\( 0.5 \times 85 = 42.5 \)[/tex].
- Since the number of offspring cannot be a fraction, typically you'd round to the nearest whole number when presenting these results in a real-world scenario. However, based on the provided answer, it's 42.5.
Given the context, the last piece of information seems to suggest summarizing the findings for black fur and black eyes.
### Completed Sentences:
In the dihybrid cross, [tex]\(\frac{9}{16}\)[/tex] of the parents had black fur and black eyes.
The offspring of the parents had black fur and black eyes at a frequency of approximately 42.5 out of 85 offspring.
The full explanation in a summarized manner would be:
In the dihybrid cross, [tex]\(9 / 16\)[/tex] of the parents had black fur and black eyes. The offspring with black fur and black eyes made up approximately 42.5 out of 85 offspring, which corresponds to 50%.
