1Explaining differences/ Explaining similarities Nature VS nurtureExplaining differences/ Explaining similarities
2QuestionIf it were possible, would you want to take a genetic test telling you which diseases you are likely to suffer from later in life?If you or your partner were pregnant- would you want the unborn child tested for genetic defects?
3Nature when biology determines characteristic's Biological determinism
4Dominant and Recessive Genes The Tower of London46 Books23 donated by mother23 donated by fatherBooks are ChromosomesChromosomes made from dnaGenes are small areas of dna30,000 genes per chromosome
5Dominant vs. recessive genes Dominant genesRecessive genesCharacteristic is always presentTwo recessive genes must be paired in order for the characteristic to be present
6Consider Dolly….Would a human clone’s adult personality mimic the person donating the genetic code? or Would he/she be unique?
7Heredity=When biology determines characteristics Genetic PredispositionGenetic DeterminismHumans are born with a likelihood toward certain characteristicsDoes not mean “Born with”Usually needs something from the environment to activate- (diathesis-stress model)Common genetic predispositions….body weight-alcoholism-Alzheimer’s-SchizophreniaThe idea that genes determine characteristicsGenotype= “full” heredityPhenotype= “observed” propertiesCommon genetic abnormalities.. Down Syndrome, Williams Syndrome, Color blindness, PKU
8How do genes and the environment interact? PKU= PhenylketonuriaOccurs when parents pass along a defective gene
15Nature enables nurture and Nurture enables nature Critical Period: An important time in development where development needs to happen or it will be delayed or dysfunctional Prenatal influences: German measles, birth defects, teratogens, fetal alcohol syndrome Culture: Establish their own norms
