Consider an autosomal dominant trait with reduced penetrance and complete expressivity. What might you expect to see on a pedigree diagram for a family with all affected individuals may not have an affected parent (the trait appears to skip generations).   more than one of the options listed here  affected males always pass the trait to daughters but never to sons  only one sex displays the trait  all affected individuals have an affected parent (the trait does not appear to skip generations)

Inheritance and Mendelian Genetics

Inheritance means the passing of traits to offspring from parents. These traits could be passed either through asexual reproduction or sexual reproduction. The offspring receives the genetic material from the parents. Mendelian inheritance is a certain biological inheritance that follows the rules and principles laid down by Gregor Mendel in 1865. The initial hypothesis was considered wrong, but other inheritance theories modified the concept of inheritance and thus genetics.
