What is the most likely mode of inheritance for the trait shown in this pedigree? pleiotropic autosomal dominant X-linked dominant autosomal recessive X-linked recessive Y-linked recessive

Solution

Y- linked recessive.

Because its affecting only males so its indicating that the disease is Y-linked.

And Because only males have a Y chromosome, in Y-linked inheritance, a mutation can only be passed from father to son. So it will be Y-linked recessive.
