Document Summary
Genetic endowment + environmental forces behaviour. Nature (something we are born with) vs nurture (something we learn: environment can influence protein synthesis, genes determine range of possibilities but not the degree of expression. Hippocrates suggested that semen contains some sort of design for offspring. Mendel used garden peas: show heredity involves passing on specific organic factors. Phenotype: observable characteristics produced by that genetic endowment: can be affected by other genes and by the environment, cannot infer genotype from phenotype. Chromosome: tightly coiled molecule of dna that is partly covered by protein. Genes: dna portion of chromosomes that carry the hereditary blueprint. Alleles: alternative forms of a gene that produce different characteristics. There are no genes for a particular attribute: measure of intelligence = measure of reaction time (fast response of neurons = intelligence?) Genotype and phenotype are not identical because some genes are dominant and others are recessive. Dominant: particular characteristic that it controls will be displayed.
