Life Cycles

• Gametes are haploid, meaning they have:

  • One complete set of genes
  • One complete set of chromosomes
  • The number of chromosomes is half that of diploid cells
• Diploid cells have:

  • Two complete sets of genes
  • Two complete sets of chromosomes
  • The number of chromosomes is 46
• A diploid cell has 23 pairs of homologous pairs
• Sperm and egg are gametes
• Meiosis produces four genetically different daughter cells from one parental cell.
• Zygotes are diploid cells
• A zygote is a fertilized egg cell that results from the fusion of two haploid gametes. (sperm and egg)
