Document Summary

They are not exclusive categories as genetics and experience are never independent: hence, nature and nurture are inextricably entertwined, impossible to separate genetic influences from the environmental as they work together to determine human behaviour. Epigenetics: changes in gene expression that are due to non-genetic influences or due to experiences that do not alter the genetic code. Eg. cuddling increase expression of a gene that releases more dopamine as a result. Our genetic material is organized into genes (basic units of heredity) and they provide information to create proteins which then regulate physiological processes throughout life. Genes are made up of dna molecules which in turn are made up of nucleotides containing a t, We have 20-25k genes distributed across 23 chromosomes. If the 2 genes are different, the genes are known to be heterzygous. Behavioural genomics: the study of dna and genes and how they affect behaviour. Diseases/conditions/behaviour is a result of combinations of genes.
