PSYA01H3 Study Guide - Final Guide: Behavioural Genetics, Heredity, Cytosine
Document Summary
Sexual motivation in females is shown through clothes, males by body building/flaunting assets. Genetics has a dramatic effect on behaviour. Genes: basic units of heredity; responsible for guiding the process of creating the proteins that make up our physical structures and regulate development and physiological processes throughout the lifespan. Composed of dna, organized in pairs of chromosomes. Dna (deoxyribonucleic acid): molecule formed in a double-helix shape that contains four nucleotides: adenine, cytosine, guanine and thymine. Genotype: genetic makeup of an organism unique set of genes that comprise that individual"s genetic code (ex. Phenotype: the physical traits or behavioural characteristics that show genetic variation, ex. eye colour, size of facial features and even personality. Homozygous pair of chromosomes are the same. Heterozygous pair of chromosomes are different. Recessive gene (lowercase) tt: ex. gene for tasting is t or t. Behavioural genomics: study of dna and the ways i which specific genes are related to behaviour.
