● 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 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. ● Molecular Genetics: The subfield of biology that studies the molecular structure and function of genes. ● 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 environment studied. ● Interaction: The interplay that occurs when the effect of one factor (such as environment) depends on another faction (such as heredity). ● Epigenetics: The study of environmental influences on gene expression that occurs 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, among the range of inherited trait variations, those contributing to reproduction and survival will most likely be passed on to succeeding generations. ● Mutation: A random error in gene replication that leads to a change. ● Left Hemisphere: The left side of the brain is responsible for controlling the right side of the body. ● Right Hemisphere: The cerebral hemisphere located on the right side of the corpus callosum. The right brain controls activities on the left side of the body ● Ramachandran: Vilayanur Subramanian Ramachandran is an Indian-American neuroscientist.
