10 Genes: Our Codes for Life Chromosomes   are rodlike substances in the nucleus of a  cell which contain  DNA   ( deoxyribonucleic acid ).  Chromosomes store and transmit genetic information.

11 Genes: Our Codes for Life Segments within DNA consist of genes.    Genes  are  capable of synthesizing proteins which determine  our heredity and development.

16 Separated Identical Twins A number of studies compared  identical twins  raised  separately from birth, or close thereafter, and found  numerous  similarities . Separated Twins showed shared: Personalities & Intelligence Abilities & Attitudes Interests & Fears Brain Waves & Heart Rate

19 Adoption Studies Adoption studies,  as opposed to twin studies, suggest that  adoptees (who may be biologically unrelated) tend to be  different from their adoptive parents and siblings.    Heredity shapes personality.  Adoptees’ personalities are  more like their biological parents.

20 Adoptive Studies Another interesting fact emerges.  Adoptive studies  strongly point to the simple fact that  biologically  related children turn out to be different in a  family.  So investigators ask: Do siblings have differing experiences? Do siblings, despite sharing half of their genes, have different combinations of the other half of their genes? Ultimate question: Does parenting have an effect?

22 Temperament Studies Temperament  refers to a person’s stable, individual  differences in the quality and intensity of emotional  reactions (reactivity) or emotional excitability.  Temperament is the inborn rudiments of  personality. When we study infants, psychologists think in terms of  the temperament of the infant and not the personality.   For example, is the infant’s temperament more relaxed and  easy going. Identical twins express  similar temperaments suggesting  heredity predisposes temperament .

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
