Autosomal Dominant Pattern

Autosomal dominant traits, like sex-linked dominant traits, affect both sexes and carrier states do not exist. The key difference between an autosomal and sex-linked dominant pattern is that in the former males can transmit the trait to both sons and daughters. (Remember that males never transmit sex-linked traits to their sons.)

Examples of an autosomal dominant pattern include achondroplasia and Huntington chorea, as well as most blood group genes.
