Card Set Information
the study of the relative power and limits of genetic and environmental influences.
threadlike structures made of DNA molecules that contain the genes.
a complex molecule containing the genetic information that makes up the chromosomes.
the study of the evolution of behavior and the mind, using principles of natural selection.
twins who develop from separate fertilized eggs. They are 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.
the proportion of variation among individuals that we can attribute to genes. The heritability of a trait may vary, depending of the range of populations and environments studied.
twins who develop from a single fertilized egg that splits into two, creating two genetically identical organisms.
a random error in gene replication that leads to a change.
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.
