Behavior Genetics Flashcards
Environment
Every external influence
Chromosome
Threadlike structure made of DNA molecules that contain genes
DNA
A complex molecule containing the genetic information that makes up the chromosomes
Genes
Biochemical units of heredity that make up chromosome
Genome
Complete instructions for making an organism
Identical twins
Twins who develop from a single fertilized egg that splits in two
Fraternal twins
Twins that develop from separate fertilized eggs
Molecular genetics
Subdued of biology
Studies molecular structure and the function of genes
Heritability
Proportion of variations among individuals that we can attribute to genes
Interaction
Interplay that occurs when the effect of one factor depends on another
Epigenetics
Study of environmental influences on gene expression that occur without a DNA change
Behavior genetics
Study of relative power and limits of genetic and environmental influences on behavior
