Recessive sex linked disorders are more common in males than in females because
X-linked recessive diseases usually occur in males. Males have only one X chromosome. A single recessive gene on that X chromosome will cause the disease. The Y chromosome is the other half of the XY gene pair in the male. However, the Y chromosome doesn't contain most of the genes on the X chromosome. Because of that, it doesn't protect the male. Diseases such as haemophilia and Duchenne muscular dystrophy occur from a recessive gene on the X chromosome. Thus, the correct answer is option B.
