  1. Problems with evolved mechanisms that are no longer necessary
  2. Mitosis vs Meiosis
    • cells duplicates itself 
    • cell divides once
    • forming two cells 
    • vs
    • cell duplicates its chromosomes
    • cell divides twice 
    • forming four cells
    • (cell division occurs to form eggs and sperm)
  3. Chromosome pairs for males 

    Chromosome pairs for females
    XY  (23 pair) 

    XX  (23 pair)

    males Y chromosome is smaller than a females X chromosome
  4. difference between identical and fraternal twins
    • Identical develop from a single fertilized egg
    • more conduct problems
    • more similar genetically

    • fraternal twins develop from separate eggs
    • less conduct problems
    • less similar genetically
  5. Phenotype
    consist of observable characteristics 

    • height
    • weight
    • hair color

  11. Passive Genotype-Environment Correlation
    correlation exists when the natural parents who are genetically related to the child, provide rearing environment for the child
  12. Epigenetic View
    states that development reflects an ongoing, bidirectional interchange between heredity and the environment
