Ch. 4 Nature vs Nurture Flashcards
behavior genetics
study of relative power and limits of genetic and environmental influences on behavior
hereditary
genetic transfer of characteristics from parent to offspring
environment
every nongenetic influence
chromosomes
threadlike structures made of DNA molecules that contain genes
DNA
complex molecule containing genetic information that makes up chromosomes
genome
complete instruction for making an organism
genes
biochemical unit of hereditary that makes up the chromosomes, small segment of DNA capable of synthesizing proteins
identical twins
individuals who develop from a single fertilized egg
fraternal twins
individuals who develop from separate fertilized eggs
heritability
proportion of variation among individuals in a group that we can attribute to genes
interaction
interplay that occurs when the effect of one factor depends on the other
molecular genetics
studies molecular function and structure of genes
molecular behavior genetics
study of how structure and function of genes interact with our environment to influence behavior
epigenetics
study of molecular mechanisms by which environments can influence gene expression
evolutionary psychology
study of evolution of behavior and the mind
mutation
random error in gene replication that leads to a change
