Document Summary

Our physical development, including our development of our nervous system, is in large part directed by an elaborate genetic blue print passed to us by our parents capabilities determine our behaviour. These biological characteristics set limits on our behavioural. Genetic endowment combines with environmental forces to. Gregor mendel marked the beginning of modern genetic history. Showed that heredity involves the passing on of specific organic. The offspring of one set of parents do not inherit all the same. Genotype: the specific genetic makeup of an individual. Phenotype: the observable characteristics produced by that. Genotypes are present from birth and never change. Phenotypes can be effected by the environment and other genes. Chromosome: is a tightly coiled molecule of deoxyribonucleic acid (dna) that is partly covered by protein. The dna is so tightly coiled that if the dna in a single human cell were stretched out, it would be almost 2 metres long blueprint in units called genes.
