complete solutions passed
Genotype
Set of genes a person inherits; genetic makeup of an organism
Phenotype
Observable properties of the body and behavior; characteristics resulting from genotype and
environment
Gene-By-Environment Interaction (GxE)
Genetic predisposition predicts outcome depending on environment
Gene-Environment Correlation (rGE)
Genetic predisposition correlates with characteristics of environment
Genetic Inheritance
Studying genetic differences in specific traits
Single-gene traits
,Differences based on alleles on a single section of a gene
Polygenic traits
Multiple genes underlie variations in a given trait
Epigenetics
Interactions between genes and environment that regulate gene expression; influences
phenotype
Artificial Selection
Human-controlled selective breeding
Natural Selection
Nature controls breeding based on survival and reproduction
Variation
Differences between individuals in a species
Inheritance
Some variations are heritable, passed down through genes
, Functionalism
Explains traits in terms of their function or what they accomplish
Sexual Selection
Natural selection focused on traits helpful for reproduction
Intrasexual competition
Competition between members of one sex for access to the other sex
Intersexual competition
Mate choice based on specific preferences
Parental Investment Theory
Difference in investment between males and females affects mate selection
Evolutionary Psychology
Applies principles of natural and sexual selection to human behavior
