| Question | Answer |
| environment | every nongenetic influence, from prenatal nutrition to the people and things around us. |
| behavior genetics | the study of the relative power and limits of genetic and environmental influences on behavior. |
| chromosomes | threadlike structures made of DNA molecules that contain the genes. |
| DNA (deoxyribonucleic acid) | a complex molecule containing the genetic information that makes up the chromosomes. |
| genes | the biochemical units of heredity that make up the chromosomes; segments of DNA capable of synthesizing proteins. |
| genome | the complete instructions for making an organism, consisting of all the genetic material in that organism’s chromosomes |
| identical (monozygotic) twin | develop from a single fertilized egg that splits in two, creating two genetically identical organisms. |
| fraternal (dizygotic) twins | develop from separate fertilized eggs. They are genetically no closer than ordinary brothers and sisters, but they share a prenatal environment. |
| interaction | the interplay that occurs when the effect of one factor (such as environment) depends on another factor (such as heredity). |
| epigenetics | the study of environmental influences on gene expression that occur without a DNA change. |
| evolutionary psychology | the study of the evolution of behavior and the mind, using principles of natural selection. |
| natural selection | the principle that those chance inherited traits that better enable an organism to survive and reproduce in a particular environment will most likely be passed on to succeeding generations. |
| mutation | a random error in gene replication that leads to a change. |
