Document Summary

Chapter 4 genes, evolution, and behaviour. Polygenic transmission: genes combine their influences to create a single phenotypic trait. Recombinant dna: use enzymes to cut dna into pieces, combine the wanted piece with dna from another organism. Insert combination into a host organism (bacteria: new dna combination divide inside host cell, example: human growth hormone. Insertion, alteration, or removal of genes to treat disease. Tay- sachs: recessive gene, dysfunctional protein, breaks down fats in brain, rare, early onset. Seizures, blindness, mental dysfunction, death in early childhood. Lethal early death: those with sickle cell trait are immune to malaria, malaria lethal. Some europeans are immune to hiv: genetic mutation that prevents hiv from entering white blood cells, 2 copies of mutation. Genetic counselling: offer understanding medical information about genetic disorders, help make decisions, health, pregnancies, child"s health care, etc. Adoption study: person who was adopted is compared with biological and adoptive parents.
