Nature or nurture is a false dichotomy, it should be nature and nurture. Hippocrates provided rst semi-correct answer suggested semen contains not body parts, rather some sort of design for the formation of offspring. Gregor mendel con rmed this theory with experimentation with garden peas he showed that heredity involves the passing on of speci c organic factors, not simple blending of parents" characteristics which explains the differences seen between brothers and sisters. Genotype: the speci c makeup of an individual (g for genetic) E. g. geneticists discovered that chickens have retained the genetic code for teeth, but the code is prevented from being expressed hence the term hen"s teeth (scarcity) Phenotype: the observable characteristics produced by that genetic endowment (p for psychical) Can be affected by other genes and the environment. Chromosome: tightly coiled molecule of dna that is partly covered by protein that contain the genes.
