Question

Using the pedigree in the image, what type of inheritance pattern is most likely?

• A. Autosomal dominant
• B. Autosomal recessive
• C. Sex-linked recessive
• D. Holandric

Answer 1

The correct option is C Sex-linked recessive

In the given Pedigree we can see that only the males are affected therefore the condition is sex-linked that reveals itself in the next generation and not the parents which go on to show that the female number one is the carrier of the trait and passes that trait to the following generations.

The condition is recessive because both of the parents are not suffering from the disease but the children are.

So, the correct option is 'sex-linked recessive'
