Document Summary

Behaviour genetics: study of the relative power and limits of genetic and environmental influences on behaviour. 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: a complex molecule containing the genetic information that makes up the chromosomes. Genes: biochemical units of heredity that make up the chromosomes; segments of dna capable of synthesizer. Genome: 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 (monozygotic) fertilized egg that splits in two, creating two genetically identical organisms. Fraternal twins: twins who develop from separate (dizygotic) fertilized eggs. They are genetically no closer than brothers and sisters, but they share a fetal environment temperament: individual"s characteristic emotional reactivity and sensitivity. Molecular genetics: subfield of biology that studies the molecular structure and function of genes.
