1. Describe the significance of the autosomal recessive inheritance pattern in
relation to cystic fibrosis.
Cystic fibrosis is linked to the X chromosome, affecting males more
severely than females.
Cystic fibrosis is inherited in an autosomal recessive manner,
meaning that an individual must inherit two copies of the mutated
gene to express the disease.
Cystic fibrosis is inherited in an autosomal dominant manner, requiring
only one copy of the mutated gene.
Cystic fibrosis can be inherited from one parent only, regardless of the
gene's location.
2. What metabolic process allows muscles to continue performing in the
absence of oxygen?
Phosphocreatine breakdown
Lactic acid fermentation
Anaerobic glycolysis
Aerobic respiration
3. Describe the significance of identifying a proband in genetic counseling.
Identifying a proband helps to trace the inheritance pattern of a
genetic condition within a family.
Identifying a proband only focuses on maternal lineage.
Identifying a proband is only necessary for rare diseases.
, Identifying a proband is irrelevant in genetic counseling.
4. What inheritance pattern is associated with cystic fibrosis?
X-linked recessive
Autosomal recessive
Autosomal dominant
X-linked dominant
5. Describe how Prader-Willi syndrome is related to the concept of genomic
imprinting.
Prader-Willi syndrome is an example of autosomal dominant
inheritance affecting chromosome 7.
Prader-Willi syndrome is caused by environmental factors rather than
genetic ones.
Prader-Willi syndrome is caused by the loss of function of genes on
the paternal chromosome 15 due to genomic imprinting.
Prader-Willi syndrome results from a mutation in a single gene
inherited from the mother.
6. The sodium potassium pump moves sodium and potassium ions across the
plasma membrane by
Endocytosis
active transport
cotransport
facilitated transport
Exocytosis
