    Monogenic transmission
  10. The process by which many genes interact to create a single characteristic
    polygenic transmission
  11. The extent to which a characteristic is influenced by genetics
  12. Twins that develop from two differnt eggs fertilized by two different sperm
    Fraternal twins
  13. Twins that develop from a songle fertilized egg that splits into two independent cells
    Identical twins
  14. Research into hereditary influnce on twins, both identical and fraternal, who were raised apart and who were raised together
    Twin-Adoption Studies
  15. Method of studying heritability by comparing genetic markers
    Gene-by-enviroment interaction research
  16. The entire genetic make up of an organism
  17. Study of changes in the way genes are turned on or off without a change in the DNA sequence
  18. THe organisms observed characteristics
  19. genes occur in pairs, or alternate forms of each other, called
    a. chromosomes
    b. alleles
    c. base-pairs
    d. ribosomes
  20. Why are twin-adaoptions studies powerful ways to untangle the effects of genes and enviroment on thought and behavior?
    a. because they allow both genetic and enviromental similarity to be compared and contrasted
    b. because twins share genes
    c. because of epigenetics
    d. because they allow researchers to experimentally manipulate genetic and environmental similarity
  21. Nurturing behavior in rats can produce, calmer, less stressed offspring because genes that are involved in stress reactions are tuned off. This is an example of
    a. epigentics
    b. genetic engineering
    c.recessive genes
    d. dominant genes
