Twins who develop from a single fertilized egg that splits in 2, creating 2 genetically identical organisms
The study of the relative power and limits of genetic and environmental influences on behavior
The subfield of biology that studies the molecular structure and function of genes
The principle that, among the range of inherited trait variation, those that lead to increased reproduction and survival will most likely be passed on to succeeding generations
The proportion of variation among individuals that we can attribute to genes; heritability of a trait may vary, depending on the range of populations and environments studied
A complex molecule containing the genetic information that makes up the chromosomes
The interplay that occurs when the effect of 1 factor (such as environment) depends on another factor (such as heredity)
A random error in gene replication that leads to a change
Threadlike structures made of DNA molecules that contain the genes
The study of the evolution of behavior and the mind, using principles of natural selection
Twins who develop from separate fertilized eggs; genetically no closer than brothers and sisters, but they share a fetal environment
The biochemical units of heredity that make up the chromosomes; segments of DNA capable of synthesizing a protein
The complete instructions for making an organism consisting of all the genetic material in that organism’s chromosomes
