AP Psych

• every non-genetic influence, from prenatal nutrition to the ppl and things around us
• influences half of development

• the study of the relative limits and influences of genes and environment on behavior
• behavior geneticists study our differences and weight the effects of heredity and environment

• threadlike structures made of DNA molecules the contain the genes
• there are 23 per parent totalling in 46

• a complex molecule that contains genetic information that makes up chromosomes
• Deoxyribonucleic acid

• Biochemical units of heredity that make up chromosomes; a segmen tof DNA capable of sythesizing protien
• eveybody had about 30,000 or of these gene words, a self replicating unit capable of protien synthesis

• the complete instructions for making an organism, consisting all of the genetic material in an organism's chromosomes
• DNA sequence (gattaga)

• twins who develop from a single fertilized egg that splits in two, creating to geneticall, identical organisms
• genetically identical: usually have the same cultural background too

• twins who develop from seperate fertilized eggs they are genetically no closer that brohers and sisters, but they share a fetal environment
• The shared environment has a bigger effect on similarity that genetics.

• A person's characteristic reactivity and intensity
• *Exceptionally inhibited and fearful 2-year olds often sre still relatively as shy as 8-year olds; 1/2 will become introverted adolescents

• the proportion of variation among individuals that we contribute to genes that we contribute to genes, the heritability of a trait may vary depending on the range of populations and environmnets studied
• ananlyzes the diffs among ppl it cannot attribute genetic percentile influences on the traits of an individual
• as environments become more similar, heredity as a source of differences nescessarily becomes more important

• in psychology, it occurs when the effect of one factor (such as environment) depends on another factor (such as heredity)
• forget nature vs. nurture its nature VIA nurture

• a subfield of biology that studies the molecular structure and function of genes
• they try to find specific genes influencing behavior

• the study of the evolution of behavior and the mind, using principles of natural selection.
• focuses on what makes usu so alike as humans

• the principle that, among the range of inherited trait variations, reproduction and survival will be most likely passed on to succeeding generations
• Belyaev and Trut used artificial selection to breed docile foxes

• a random error in the gene replicating procedd that leads to change
• without this, natural selsection wouldn't exist

in psychology, the biosocially influenced characteristics by which ppl define male and female
