AP Psychology unit 3C Flashcards

5058917405	Behavior genetics	the study of the relative power and limits of genetic and environmental influences on behavior	0
5058917406	environment	every non-genetic influence, from prenatal nutrition to the people and things around us	1
5058917407	chromosomes	threadlike structures made of DNA molecules that contain the genes	2
5058917408	DNA	a complete molecule containing the genetic information that makes up the chromosomes	3
5058917409	Genes	A complex molecule that make up the chromosomes; segments of DNA capable of synthesizing a protein	4
5058917410	genome	the complete instructions for making an organism, consisting of all the genetic material in that organism's chromosomes	5
5058917411	Identical twins	twins who develop from a single fertilized egg that splits in two, creating two genetically identical organisms	6
5058917412	fraternal twins	twins who develop from separate fertilized eggs. they are genetically no closer than brothers and sisters, but they share a fetal environment	7
5058917413	heritability	the proportion of variation among individuals that we can attribute to genes. this may vary, depending on the range of populations and environments studied	8
5058917414	interaction	the interplay that occurs when the effect of one factor depends on another factor	9
5058917415	molecular genetics	the subfield of biology that studies the molecular structure and function of genes	10
5058917416	evolutionary psychology	the study of the roots of behavior and mental processes using the principles of natural selection	11
5058917417	natural selection	the principle that, among the range of inherited trait variations, those contributing to reproduction and survival will most likely be passed on to succeeding generations	12
5058917418	mutation	a random error in gene replication that leads to a change	13
5058917419	one major criticism of the evolutionary perspective in psychology	it analyzes after the fact using hindsight	14
5058919023	temperament	An innate, genetically influenced "baseline" of personality. basic emotional style that appears early in development and is largely genetic in origin	15
5059185063	active/expressed genes	environmental events "turn on" genes; genes that are expressed	16
5059185681	protein molecules	the building blocks of physical development	17
5059189324	separated twins	twins who are separated at birth	18
5059191937	biological vs. adoptive relatives	adopted children are more similar to genetic relatives than their enviroment/ nurture areas	19
5059195509	genetic relatives	biological parents and siblings	20
5059195510	environmental relatives	adoptive parents and siblings	21
5059196868	self-regulating	genes are self-regulating	22
5059198369	gender differences in sexuality	frontal lobes are thicker in women than in men men have a lower threshold for percieving warm responses as a sexual come-on	23
5059199633	natural selection and mating preferences	Darwin's ideas on natural selection and evolution the conditions of the environment favor the reproductive success of individuals with certain physical and behavioral characteristics. social darwinism	24
5059200863	critiques of evolutionary perspective	Buss et al. study: Although studies seem to highlight the differences between men and women, they are actually very similar in looking for two specific traits: kindness and intelligence	25
5059202259	reflections on nature v. nurture	genes form us. but, our experiences also form us.	26
5059202260	phenotype	How a trait appears or is expressed	27
5059202261	genotype	An organism's genetic makeup	28
5059204757	dominant gene	A gene that is expressed in the offspring whenever it is present	29
5059208304	recessive gene	Gene that is hidden when the dominant gene is present	30
