Question
A pedigree diagram shows males and females affected equally, heterozygotes have a normal phenotype, and affected children can have unaffected parents.Group of answer choicesautosomal recessive disordersex-linked disorderautosomal dominant disordermitochondrial disorder
Solution
The description provided in the question suggests an autosomal recessive disorder. Here's why:
-
"Males and females affected equally": This suggests that the disorder is not sex-linked, as sex-linked disorders often affect one sex more than the other.
-
"Heterozygotes have a normal phenotype": This indicates that the disorder is recessive, not dominant. In a dominant disorder, heterozygotes would show the disorder.
-
"Affected children can have unaffected parents": This is also characteristic of a recessive disorder. If the disorder were dominant, an affected child would have to have at least one affected parent.
