A pedigree diagram shows heterozygotes have a normal phenotype and affected children can have unaffected parents.Group of answer choicesautosomal recessive disorderautosomal dominant disorder
Solution

-
"Affected children can have unaffected parents": This is also a characteristic of recessive disorders. Unaffected parents can be carriers of the disease (i.e., they are
