Biopsychology Worksheet 3.4 – Applied Behavioral Genetics A bit more on Heritability: 1. Can we ask “how much” of our behavior is due to genes and “how much” is due to environment? Why or why not? No since both work interchangeably 2. Decide whether or not we can say the following, and what each of the following mean: a. Personality is 80% heritable.: variance The genetic framework for our personalities can be manipulated by our experiences in life. . Personality is a complex trait.

    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.

    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.
