Chaper 3 - Nature Vs. Nurture Flashcards
(28 cards)
The most important of the male sex hormones. Both male and females have it, but the additional __________ in males stimulates the growth of the male sex organs in the fetus and the development of the male sex characteristics during puberty.
Testosterone
A set of expectations about a social position, defining how those in the position ought to behave
Role
The sex chromosome found only in males. When paired with an __ sex chromosome from the mother, it produces a male child.
Y Chromosome
The sex chromosome found in both men and women. Females have two, males have one.
X Chromosome
Self replicating ideas, fashions, and innovations passed from person to person
Memes
The buffer zone we like to maintain around our bodies.
Personal space
An understood rule for accepted and expected behavior. These prescribe “proper” behavior
Norm
The ending behaviors, ideas, attitudes, and traditions shared by a large group of people and transmitted from one generation to the next.
Culture
The subfield of biology that studies the molecular structure and function of genes
Molecular genetics
The dependence of the effect of one factor on another factor
Interaction
The proportion of variation among individuals that we can attribute to genes.
Heritability
A persons characteristic emotional reactivity and intensity
Temperament
Twins who develop from separate eggs. They are no genetically closer than brothers and sisters, but they share a fetal environment
Fraternal twins
twins who develop from a single fertilized egg that splits in two, creating two genetically identical organisms
Identical twins
Every nongenetic influence, from prenatal nutrition to the people and things around us
Environment
The study of relative power and limits of genetic and environmental influences on behavior
Behavior genetics
In psychology, the characteristics, whether biologically of socially influenced, by which people define male and female
Gender
The study of the evolution of behavior and the mind, using principals of natural selection.
Evolutionary psychology
A random error in gene replication that leads to a change in the sequence of nucleotides; the source of all genetic diversity
Mutation
The principle that, among the range of inherited trait variations, those that lead to increased reproduction and survival will most likely be passed on to succeeding generations
Natural selection
The complete instructions for making and organism, consisting of all the genetic material in its chromosomes.
Genome
The biochemical units of hereditary that make up the chromosomes; a segment of DNA capable of synthesizing a protein
Genes
A complex molecule containing the genetic info that makes up the chromosomes
DNA
Threadlike structures made of DNA molecules that contain the gene
Chromosomes
