Document Summary

Genetically influenced behaviour is not nature or nurture, rather nature and nurture. How favourable or unfavourable environmental conditions can affect genetically inherited potential. Heredity: passage of characteristics from parents to offspring through genes. Heritability: how much variation in a characteristic within a population can be attributed to genetic differences. Not all genes are used (contradict with others, environment never calls them out) Gregor mendel"s experimentation with pea plants in the 1860s showed that heredity was the passing on of specific traits instead of a blending of the parents" characteristics. Genotype: the specific genetic makeup of the individual. Phenotype: the observable characteristics produced by that genetic endowment. Egg and sperm carry chromosomes: dna (material of heredity, which has units called genes that carry information about your characteristics and traits) Every cell in the human body has 46 chromosomes, except for the sex cells (sperm or egg) which only have 23 chromosomes.
