1. Genetic Basic Concepts

Key Concepts & Definitions

  • Gene: A segment of DNA that encodes a specific protein or RNA, serving as the basic unit of heredity.
  • Allele: Alternative forms of a gene located at the same locus on homologous chromosomes, responsible for variations in a trait.
  • Chromosome: A structured DNA molecule carrying genetic information; humans have 23 pairs of chromosomes.
  • Genotype: The complete set of genes an organism possesses; the genetic makeup.
  • Phenotype: The observable physical or biochemical traits of an organism resulting from its genotype and environment.
  • Mutation: A change in the DNA sequence that can lead to genetic variation, which may be neutral, beneficial, or harmful.
