Question
The trait represented in the following pedigree is expressed only in the males of the family. Is the trait Y linked? Why or why not? If you believe that the trait is not Y linked, propose an alternative explanation for its inheritance.
Step 1
Y-linked inheritance, also known as holandric inheritance, occurs when a gene, trait, or disorder is transferred through the Y chromosome. Since males have one X and one Y chromosome and females have two X chromosomes, Y-linked traits are only passed from father Show more…

The genetic trait shown in the family below is X-linked dominant because: a) The trait appears in every generation in the family. b) The trait appears in every generation in the family, and some males show this trait. c) A male parent passed on this trait to all his daughters, but not to his sons. d) This trait skips a generation in males
Other than the fact that a Y-linked trait appears only in males, how does the pedigree of a Y-linked trait differ from the pedigree of an autosomal dominant trait?
