### Genetic Questions on X-linked Colorblindness and Recessive Mutations in Mice

**Question 6: X-linked Colorblindness**

A man with X-linked colorblindness marries a woman with no history of colorblindness in her family. Their daughter marries a normal man, and their daughter also marries a normal man. This last couple has already had a child with colorblindness.

**Questions:**
A) What is the chance that the next child will be colorblind?

B) What is the chance that this last couple will have an affected daughter?

**Question 7: Recessive Mutations in Mice**

Two strains of mice are homozygous for a recessive mutation that causes eyes to be small; the two phenotypes are indistinguishable. The mutation in one strain is called "little eye," and the mutation in the other strain is called "tiny eye." How do you determine if two recessive mutations are alleles of the same gene?

### Explanation

- **X-linked Colorblindness:**  
  - **Determine genetic inheritance:** Analyze the X-linked inheritance pattern across generations for accurate predictions.
  
- **Recessive Mutations in Mice:**  
  - **Allele Testing Approach:** Use cross-breeding of the strains and observe F1 offspring to determine allelism based on phenotype expressions.
