A geneticist is studying the correlation between disease D and mutations on gene A or mutations on gene B. She collects data from 1,000 mice and records it in the above Venn diagram.

Question

What percentage of mice who do not have the disease do have the gene A mutation?

A.
1.2%
B.
2.1%
C.
3.8%
D.
6.8%

Answer 1

To determine the percentage of mice who do not have the disease but have the gene A mutation, we first need to identify the relevant numbers from the Venn diagram data that you referenced. Since the specifics of the Venn diagram are not provided, I will outline how to calculate the percentage based on hypothetical values.

1. Total number of mice: 1,000 mice.
2. Number of mice having disease D: Assume this number is represented by some total value, say \(X\).
3. Number of mice without disease D: This would be \(1,000 - X\).
4. Number of mice with gene A mutation (regardless of disease): Let’s say this is \(Y\).
5. Number of mice without disease D who have gene A mutation: Assume this number is \(Z\).

With these variables, the percentage of mice who do not have the disease but have the gene A mutation can be calculated as:

\[ \text{Percentage} = \left( \frac{Z}{1,000 - X} \right) \times 100 \]

If you provide specific numbers from the Venn diagram, I can help you with the precise calculation. However, based on the options provided, feel free to follow the formula with your obtained values.
