Question | Answer |
---|---|
Behavior Genetics | The study of the relative power and limits of genentic and environmental influences on behavior. |
Environment | Every non-genetic influence, from prenatal nutrition to the people and things around us. |
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 a protein. |
Genome | The complete instructions for making an organism, consisting of all the genetic material in that organism's chromosomes. |
Identical Twins | Twins who develop from a single fertilized egg that splits in two, creating two genetically identical organisms. |
Fraternal Twins | Twins who develop from separate fertilized eggs. They are genetically no closer than brothers and sisters, but they share a fetal environment. |
Heritability | The proportion of variation among individuals that we can attribute to genes. The heritability of a trait may vary, depending on the range of populations and environments studied. |
Interaction | The interplay that occurs when the effect of one factor (such as environment) depends on another factor (such as heredity). |
Molecular Genetics | The subfield of biology that studies the molecular structure and function of genes. |
Evolutionary Psychology | The study of the evolution of behavior and the mind, using principles of natural selection. |
Natural Selection | The principle that, among the range of inherited trait variations those that lead to increased reproduction and survival will most likely be passed on to succeeding generations. |
Mutation | A random error in gene replication that leads to a change. |
