Question

which inheritance pattern is shown in the following pedigree? sex - linked dominant autosomal dominant sex - linked recessive autosomal recessive

Explanation:

In an autosomal dominant inheritance pattern, affected individuals have at least one affected parent. In the given pedigree, the trait appears in multiple generations, and affected individuals (both males and females) have affected parents. This is characteristic of autosomal dominant inheritance. In sex - linked patterns (dominant or recessive), there would be a more pronounced sex - bias in the inheritance (e.g., more males affected in sex - linked recessive). In autosomal recessive, two unaffected parents can have affected children (which is not the case here as affected individuals have affected parents).

Answer:

autosomal dominant
