Question

complete the passage. some genetic disorders are said to “skip a generation,” but they are present in a parent, known as a , who has a copy of the allele for the disorder that is by another allele. the only disorders that cannot be inherited in this way are . in disorders that are , only one parent, the , can pass on the disorder without expressing it. carrier autosomal recessive sex - linked mother autosomal dominant father masked enhanced

Explanation:

A carrier is an individual who has a copy of a recessive allele for a disorder that is masked by a dominant allele. Autosomal - dominant disorders cannot skip a generation as only one copy of the allele is needed for the disorder to be expressed. In autosomal - recessive and sex - linked disorders, a carrier (either mother or father) can pass on the disorder without showing symptoms.

Answer:

carrier, masked, autosomal dominant, autosomal recessive or sex - linked, carrier (either mother or father)
