AIIMS 2018 Botany Inheritance Patterns MCQ Question

Option A is correct because hemophilia is indeed an X-linked recessive disorder, primarily affecting males who have only one X chromosome. In males, a single mutated gene on the X chromosome leads to the condition, while females, having two X chromosomes, can be carriers without exhibiting symptoms unless both X chromosomes carry the mutation. Other options are not applicable as they do not provide relevant information or alternative answers regarding the inheritance pattern of hemophilia. Understanding X-linked inheritance is crucial for recognizing how certain genetic disorders are transmitted through families, particularly those that predominantly affect males.
