Document Summary

Developmental psychology: developmental psychology concerns systematic changes over the life course. Prenatal issues: inheritance of characteristics, 50% from mom, 50% from dad (genetic makeup and potential to resemble each parent) Chromosomes with genes: chromosome pair gene pairs, alleles- gene versions, dominant vs recessive. Mz (monozygotic) twins are 100% the same genetically (identical twins) (1 origin) Dz (dizygotic) twins are 50% the same genetically on average (fraternal twins) (2 origins: key assumption: twins are treated about as much alike if they are dz as if they are mz. Correlate mz pairs with each other, same-sex dz pairs with each other. Linking some particular gene to some outcome (e. g. , category of disorder) Linking some particular gene to some biological process (e. g. , neurotransmitter: complex in how genes influence cells, after conception, other pre-natal influences, biological entities can pass through the semi permeable membrane, disease organisms and chemicals can create problems. Biological and chemical entities can cross into fetal blood.
