**Question 26:**
In three sentences, explain why hemophilia primarily affects males more than females.
- **Hemophilia is an X-linked recessive disorder, meaning the gene responsible for the condition is located on the X chromosome. Males have only one X chromosome, so if they inherit the hemophilia allele, they will express the condition. Females have two X chromosomes; they must inherit two copies of the allele (one from each parent) to manifest the disorder, making it less common in females.**
