Answer 1

Answer:

X linked dominant.

Explanation:

The autosomal disease are not specifically affect the individual sex and may affect both the males and females in nearly equal proportion. X linked disease affects to the specific sex only whether male or female.

Bob has the skin disease and her wife is normal. All there sons are normal but daughters are affected by the disease. This might occur that the disease gene is located on the X chromosome of Bob. This X chromosome is transferred to all the daughters and daughters shows the disease that means the gene of the disease is dominant in nature.

Thus, the correct answer is option (b).
