Why do X-linked disorders (like Duchenne Muscular Dystrophy) affect males more often than females?

• Females have two X chromosomes, which protects them from the disorder.
• X-linked disorders are more common in females due to hormonal differences.
• Males are less likely to inherit X-linked disorders from their mothers.
• Males are more affected because they have only one X chromosome, so a single mutated gene causes the disorder.
