Document Summary

Genetics & epigenetics interact with the environment to shape health/wellbeing. Genes control characteristics, 23,000 genes in each nucleus of our body. Genotype: specific genetic material on individual chromosomes. Phenotype: the observed characteristic of that genetic trait. (what"s. Polygenic inheritance: many genes influence a trait. Multifactorial inheritance: genes and environment influence a trait. Mitochondrial inheritance: inherit genes from the mother"s egg. Polygenic: a mix of two parental genes. Height, eye & skin colour, body type, personality. Recessive genes: the less dominant form of a gene. Flat feet, blonde & red hair, rh-negative. Epigenetics: study of changes of an organism from modification of gene. Epigenetic markers regulate gene expression by turning genes on/off, Ethology: genetically-determined survival behaviours that are assumed to have. Ex. genes for crying in an irritating manner an infant"s chance of survival. Behaviour genetics: traits are influenced by genes; when related people are more. Evolutionary psychology: the view that genetically-inherited cognitive social traits.
