Document Summary
Class notes (nature side) - september 23, 2010 1. Correlational research (no cause/effect: study cause/effect by random group/sample assignment (in experimental/control groups) Theory guided research (should choose appropriate design; questionnaires might not be appropriate for all ages) Creative notion = idea of not averaging the traits from the mother/father in the offspring. Offspring didn"t indicate average of traits of parents. Males are males; not average of female/males. Transmitted discretely from one generation to the other. Tt (tall) + tt (tall) + tt (tall) + tt (short) Phenotype = characteristics that individual portrays (what they look like; observational feature) Genotype = genetic composition responsible for that phenotype. Some genes are dominant genes (t), some genes are recessive genes, only be obvious from phenotype/appearance if there were 2 recessive genes. If there"s 1 dominant gene, that will be expressed in genotype, therefore looks tall. Genes set a potential/limits; but environment determines if those limits are achieved.
