  • Which autosomal dominant disorder is characterized by polydactyly?
    Polydactyly is an autosomal dominant disorder, requiring only one dominant allele for expression.
  • How are autosomes different from sex chromosomes?
    Autosomes are non-sex chromosomes that determine traits not related to gender, while sex chromosomes determine gender-related traits.
  • How can a child inherit cystic fibrosis if neither parent has the disease?
    Cystic fibrosis is autosomal recessive, so a child can inherit it if both parents are carriers of the recessive allele.
  • What is true about the inheritance pattern of autosomal recessive traits?
    Autosomal recessive traits often skip generations because they require two recessive alleles for expression.
  • Which genetic disorders are inherited in an autosomal dominant fashion?
    Polydactyly is an example of a genetic disorder inherited in an autosomal dominant fashion.
  • What is required for an autosomal recessive disorder to be expressed?
    An autosomal recessive disorder requires two recessive alleles for expression.
  • What is a characteristic feature of autosomal dominant inheritance?
    Autosomal dominant inheritance appears in every generation without skipping.
  • What is a characteristic feature of autosomal recessive inheritance?
    Autosomal recessive inheritance often skips generations.
  • What is the inheritance pattern of cystic fibrosis?
    Cystic fibrosis follows an autosomal recessive inheritance pattern.
  • What is the inheritance pattern of polydactyly?
    Polydactyly follows an autosomal dominant inheritance pattern.
