Chapter 4 Nature Nurture Flashcards
What is Heredity
The genetic transfer of characteristics from parent to offspring
What is behavioral Genetics
The study of power and limits of genetic and environmental influences on behavior
What is Molecular Genetics ?
The study of which genes are associated with which personality traits
How does the interaction of genes and the environment work
Subtle differences in one person’s genes can cause them to respond differently to the same environmental exposure as another person
What are Genes
Biochemical units of heredity that make up chromosomes
What are chromosomes
The threadlike structure made up of DNA molecules that contain the genes
What is DNA
Complex molecules containing the genetic information containing the genes
What are Genomes
The complete instructions for making up an organism
Example of What is Self-regulation
Self-regulation: Genes turn each other off in response to the environments conditions
The ability to opt in or out of a behavior
Example of What is Epigenetic
Epigenetics: The environment acts on the surface of genes to alter their activity
shortened daylight triggers animals to change fur color or to hibernate
What is Temperament
A person’s characteristic emotional reactivity and
intensity; apparent from first weeks of life and generally
persists into adulthood
What is Parent Vs Peer Influences
The different aspects of life our parents and peers influence. Parents generally influence deep characteristic traits. While friends influence our social lives and interest
Natural Selection and Mutation
results in the reduction of genetic variation through the elimination of maladaptive individuals and consequently of the mutations that caused the maladaptation
Define Primary sex characteristics
Primary: Body structures (ovaries, testes, and external genitalia) that make sexual reproduction
possible
Define Secondary sex characteristics
: Nonreproductive sexual traits such as female breasts and hips, male voice quality, and
