Document Summary
Behavioural genetics: the study of how genes and the environment influence behaviour. Behavioural genomics: the study of dna and how the ways in which specific genes are related to behaviour. Chromosomes: structure in the cellular nucleus that are line with all of the genes an individual inherits. Dizygotic twins (fraternal twins): comes from two separate eggs fertilized by two different sperm cells that share the same womb; these twins have approximately. Monozygotic twins: comes from a single ovum (egg), which makes them genetically identical (almost 100% genetic similarity. Dna (deoxyribonucleic acid): a molecule formed in a double-helix shape that contains four nucleotides: adenine cytosine, guanine and thymine. Epigenetics: changes in gene expression that occur as a result of experience and that do not alter the genetic code. Evolution: the change in the frequency of genes occurring in an interbreeding population over generations.
