Answer 1

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