The pedigrees above show the inheritance of traits. Shaded individuals have the condition; unshaded individuals do not. Carriers, if any, are not indicated. Circles indicate XX individuals and squares indicate XY individuals. Pedigree [b] is what we would expect to see for an autosomal dominant condition. Pedigree [c] is what we would expect to see for a Y-linked condition. Pedigree [a] is what we would expect to see for an X-linked recessive condition.
