3C Flashcards
The study of the relative power and limits of genetic and environmental influences on behavior
Behavior genetics
Every nongenetic influence, from prenatal nutrition to the people and things around us
Environment
Threadlike structures made of DNA molecules that contain the genes
Chromosomes
Complex molecule containing the genetic information that makes up the chromosomes
DNA
Divide a chemical units of heredity that make up the chromosomes; segments of DNA capable of synthesizing a protein
Genes
The complete instructions for making an organism, consisting of all genetic material in that organisms chromosomes
Genome
Twins who develop from a single fertilized egg that splits into, creating two genetically identical organisms
Identical twins
20 develop from separate fertilized eggs. There are genetically no closer than Brothers and sisters, but they share a fetal environment
Fraternal twins
The proportion of variation among individuals that we can attribute to genes.
Heritability
The interplay that occurs when the effect of one factor depends on another factor
Interaction
The subfield of biology that studies the molecular structure and function of jeans
Molecular genetics
Study of the evolution of behavior in the mind, using principles of natural selection
Evolutionary psychology
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
Natural selection
A random error in Gene replication that leads to a change
Mutation
