**Question 2: X-Linked Recessive Colorblindness**

My mom is colorblind, which is an *X-linked recessive* disorder. My dad has normal color vision. I have normal color vision, as does my husband. What are the chances that my son, Liam, and my daughter, Sloane, are colorblind? There are two Punnett squares provided below, one for each generation.

**Explanation of X-Linked Recessive Inheritance:**

Colorblindness is often inherited in an X-linked recessive pattern. This means the gene causing the trait or disorder is located on the X chromosome. In X-linked recessive conditions, males (XY) are more likely to be affected because they have only one X chromosome. Females (XX) are typically carriers unless they inherit two copies of the recessive allele.

**Punnett Squares Explanation:**

1. **First Generation:**
   - The first Punnett square would illustrate the genetic combination from the woman's parents. The woman inherits one X chromosome carrying the colorblind allele from her colorblind mother and one X chromosome with the normal allele from her father.
   
2. **Second Generation:**
   - The second Punnett square would show the genetic possibilities for the children of a woman with normal vision (a carrier) and her husband with normal vision. The key focus is on whether her children will inherit the colorblind allele and their chances of being either a carrier or affected.

These diagrams help visualize the inheritance pattern and calculate the probability of offspring inheriting the condition or being carriers.
