Document Summary
Genetic regulation and of growth, maturation, and performance. Cultural inheritance: environmental and social conditions (where individual been raised in, parental/social influences on growth, maturation, and performance, opportunity. Influence of parental generation on offspring = genetic influence. Despite differences in appearance, humans share ~99. 9% common genetic background: less than 0. 1% variation in genetic makeup accounts for individual uniqueness. Genetic information: gene specifies sequence of amino acids, protein synthesis, through transcription (copy/mrna) and translation. Genotype + environment > phenotype: phenotype is sensitive to the environment (sensitivity, genetic is the main influence on who and what we are today, phenotypes measured on a continuous scale, height and weight (measurement on genotype) If something that we study is similar in mz twin but not dz, there"s probably a genetic influence. 33. 3/1000 live births: fraternal boy/girl (40% of all twins, most common, fraternal girl/girl, fraternal boy/boy, identical girl/girl, identical boy/boy (least common)
