  10. Embryo
    A fertilized egg cell that has gone through mitosis
  11. Fertilization
    When the egg and sperm meet
  12. Gamete
    A sex cell, only 23 chromosomes
  13. Genotype
    All traits that are found, dominant and recessive
  14. Gymnosperm

  15. Hereditary
    Passed down from the previous generation
  16. Halploid
    A cell with a half set of chromosomes
  17. Heterozygous
    Have two different traits for the same thing
  18. Homologous Pairs
    Are pairs of chromosomes that code for the same thing
  19. Homozygous
    Having two of the same traits for one thing. (ie. two sets of chromosomes that code for blue eyes)
