  • Pleiotropy
    A phenomenon where a single gene impacts multiple, seemingly unrelated phenotypic traits in an organism.
  • Phenotype
    The observable characteristics or traits of an organism resulting from gene expression and environmental influences.
  • Mutation
    A change in the DNA sequence of a gene that can alter its function and lead to diverse physical effects.
  • Gene Expression
    The process by which information from a gene is used to synthesize functional products, influencing traits.
  • Developmental Stage
    A specific period in an organism's life when certain genes are active, affecting traits at different ages.
  • Cell Type
    A distinct kind of cell in an organism where specific genes may be active, leading to tissue-specific effects.
  • Cystic Fibrosis
    A genetic disorder caused by a single gene mutation, resulting in multiple symptoms like thick lung mucus and salty sweat.
  • CFTR
    A transmembrane protein crucial for regulating chloride ion concentration, whose mutation leads to diverse symptoms.
  • Transmembrane Protein
    A protein embedded in the cell membrane, often involved in transporting substances like ions across the membrane.
  • Chloride Concentration
    The level of chloride ions within cells or tissues, essential for fluid balance and affected in certain genetic disorders.
  • Pathway
    A series of molecular interactions within a cell that lead to a specific function or response.
  • Salt Regulation
    The control of salt levels in body fluids, which can be disrupted by gene mutations, leading to symptoms like salty sweat.
  • Lung Mucus
    A fluid in the respiratory system that can become abnormally thick due to disrupted ion regulation from genetic mutations.
