Genetics
I.B. Learning Outcomes B11- With reference to relevant research
studies, to what extent does genetic inheritance influence behavior?
I can explain how much our genes impact our behavior.
Warm-Up Questions What behaviors run in your family? Do
you think these are attributed to genetics or your environment? Give specific examples.
Genetics The Study of how genes impact the
characteristics of animals and plants.
Inheritance Each offspring inherits traits from their
parents. 46 Chromosomes – 23 from Ma, 23 from
Pa
Traits Our genes determine our physical and
psychological traits. Physical Traits: Eye Color, Nose Shape,
Height Disorders: Sickle Cell Anemia,
Hutchington Disease Behaviors/Psychological Traits?
Twins
Separated Twin Studies Identical Genetic Make Up Different Environments Look for similarities and differences
between monozygotic twins Nature or Nurture Is It All in the Genes?
Minnesota Twin Study:Bouchard et al. (1990) With a partner, you will read through the
article. As you read, work to identify the aim, method, findings, and conclusions.
Pay special attention to the question of “How much do our genes impact our behavior?” (Intelligence)
Minnesota Twin Study:Bouchard et al. (1990) What is your response to the idea that
our genes can impact our behavior? What does this say about you?
Do you find these results to be surprising? Why or why not?
Critiques of research? Limitations? Ethical concerns?
I’m Not a Look Alike!
Segal (2012) Aim: To investigate if similar physical
features impact the personality traits of humans.
Method: Sent various tests and personality surveys
to subjects from Brunelle’s Art Exhibit. Stability, openness, extroversion,
agreeableness, and conscientiousness
Segal (2012) Continued Findings: Unrelated look-alikes showed
little similarities in self-esteem or personality.
Conclusions: Physical features do not predict psychological traits.
