Genetics: describes hair color, weight, height, traits that are inherited: also refers to turning genes on and off envrioment affects genes are expressed -> how they affect our behaviour thoughts and feelings. Major development in biological revolution -> human genome project: to map entire human genome (genetic material/blueprint) Humans have only about 30k genes maybe only 20k. Geneticists are now mapping individual genomes to compare gene expression. Eventual goal -> to understand how genes and their variation affect health and illnesses. Understanding genes -> cure illnesses and diseases through gene manipulation: genome determines if a cell will be a part of one organ or another. What proteins will be made etc: chromosomes made of genes, condensed genetic material. All cells have same genetic material: gene segment of dna that codes for a certain protein. E. g. a certain gene is expressed for color in the development of a butterflie"s wings depending on the surrounding temperature.
