, pedigree analysis is a strong tool to trace the inheritance of specific traits. The text describes two representative pedigrees in Figure 4.14: (a) Autosomal dominant trait (e.g., Myotonic dystrophy), where the trait appears in every generation and affected individuals have affected parents; and (b) Autosomal recessive trait (e.g., Sickle-cell anaemia), where the trait can appear in the progeny of unaffected carrier parents . While the image is not provided here, standard questions with this phrasing typically refer to the Autosomal Dominant chart showing Myotonic dystrophy.
