Traits that are determined by a single gene are of five main types: y-linked, x-linked dominant, x-linked recessive, autosomal dominant, and autosomal recessive. how many of these modes of inheritance are possible for this pedigree? assume the gene is completely penetrant, and there is no new mutations.

Autosomal dominant is the only fit for inheritance, considering that it a person will be able to inherit a condition from the parent. And since there is no mutation in it, a NEW mutation can happen in the genes even though there is no history of it in the family.
