PSYA01H3 Chapter Notes - Chapter 3.1: Behavioural Genetics, Egg Cell, Cytosine
Document Summary
Joordens: nature vs nurture: how do nature and nurture interact to produce behaviour, genetics and experience are never independent, heredity & behaviour, genetic code: Genes: basic unit of heredity; responsible for guiding the process of creating the proteins that make up our physical structures and regulate development and physiological processes throughout lifespan: composed of segments of. Dna (deoxyribonucleic acid): molecule formed into a double-helix shape that contains four molecules (adenine, cytosine, guanine, and thymine) In pairs along chromosomes: structures in the cellular nucleus that are lined with all the genes an individual inherits (23 pairs) Each gene is a unique combination of nucleotides (atcg) which makes the genotype: genetic makeup of an organism the unique set of genes that comprise that individual"s genetic code. Phenotype: physical traits or behavioural characteristics that show genetic variation (ex: eye colour, shape & size of facial features, even personality) as well as interactions with the environment. Dna genes chromosomes nucleus cell genotype phenotype.
