1. Cell Chromosome Composition

Key Concepts & Definitions

  • Diploid cells: All body cells except gametes are diploid, meaning they contain two complete sets of chromosomes, one from each parent.
  • Gametes: Reproductive cells such as egg and sperm that are haploid, containing only one set of chromosomes.
  • Chromosome: A structure within cells that carries genetic information in the form of genes; each chromosome is a long DNA molecule.
  • Maternal chromosome: The chromosome inherited from the mother, typically found in the egg.
  • Paternal chromosome: The chromosome inherited from the father, typically found in the sperm.
