A mother is a carrier for an X-linked disease, what percentage of males will manifest the disease?

Question
the context is Martin is concerned about his future children inheriting the disease. Answer the following questions regarding inheritance patterns (you might like to use punnet squares to help you prepare your response, but they don’t need to be included in your answer). A mother is a carrier for an X-linked disease, what percentage of males will manifest the disease? And what percentage of females will manifest the disease? answer: The male offspring of the mother will have 50% will manifest the disease, and the female offspring will be the carriers of the disease with 50%
Solution
The text is in English, so here is the response:
That's correct. If a mother is a carrier for an X-linked disease, she has one normal X chromosome and one affected X chromosome. When she has children, she will pass on one of her X chromosomes to each child.
For her male children, they will receive her affected X chromosome 50% of the time, which will result in them manifesting the disease, as males only have one X chromosome.
For her female children, they will also receive her affected X chromosome 50% of the time. However, as females have two X chromosomes, they will only be carriers of the disease like their mother, rather than manifesting it, unless their father also carries the affected X chromosome.

Martin, a 25-year-old male, has recently been diagnosed with a mitochondrial disease and is seeking information. You know that mitochondrial disease is a genetic disease caused by a mutation in one of the 22 autosomal chromosomes leading to a reduced function of the mitochondria. Question 11. Martin asks if his exhaustion is associated with his disease – knowing the function of the mitochondria, what would you say to Martin (in lay terms)? (2 marks) Question 12.
