Unit 11 Review Flashcards
Threadlike structure made of DNA molecules, which contain the genes:
Chromosomes
Complex molecule containing the genetic information that makes up the chromosomes:
DNA
Biochemical units of heredity that make up the chromosomes; they are segments of the DNA molecules capable of synthesizing a protein:
Genes
Genes are active:
Expressed Genes
Features associated with it will appear if the gene is present:
Dominant Genes
Features associated with it will appear only if it is paired with another recessive gene:
Recessive Gene
Complete set of genetic instructions for making an organism:
Genome
Person’s specific genetic blueprint which is determined by the total pattern of chromosomes inherited from each parent:
Genotype
Actual characteristic a person devlops:
Phenotype
Evolutionary principle that traits that contribute to reproduction and survival are most likely to be passed on to succeeding generations:
Natural Selection
Random errors in gene replication that are the source of genetic diversity within a species:
Mutations
Study of the evolution of behavior using the principles of natural selection:
Evolutionary Psychology
Biological and social characteristics by which people define male and female:
Gender
Study of genetic and environmental influences on specific behaviors and can lead to specific behavior and mental abilities:
Behavior Genetics
Refers to every nongenetic, or external, influence on our traits and behaviors:
Environment
Develop from single fertilized egg that splits in two and therefore are genetically identical:
Identical Twins
Develop from two separate eggs fertilized by different sperm and therefore are no more genetically similar than ordinary siblings:
Fraternal Twins
Refers to a person’s characteristic emotional reactivity and intensity:
Temperament
Proportion of variation among individuals in a trait that is attributable to genetic factors. Estimates place the heritability of intelligence at about 50-70%:
Heritability
Occurs when the effects on one factor depend on another factor:
Interaction
Subfield of biology that seeks to identify the specific genes that influence specific human traits and behaviors:
Molecular Genetics
Study of environmental influences on gene expression that occur without a DNA change:
Epigenetics
Enduring behaviors, ideas, attitudes, and traditions shared by a large group of people and transmitted from one generation to the next:
Culture
Understood social prescriptions or rules for accepted and expected behavior:
Norms
Buffer zone or mobile territory that people like to maintain around their bodies:
Personal Space
Variations in ideas, fashions, and innovations passed from one person to another that cause rapid cultural mutations:
Memes
Sex chromosome found in both men and women:
X Chromosome
Sex chromosome found only in men:
Y Chromosome
Principal male sex hormone that during prenatal development, stimulates the development of the external male sex organs:
Testosterone
Culturally prescribed set of behaviors expected of those who occupy a social position:
Role
Culturally prescribed set of behaviors for male and females:
Gender Role
One’s personal sense of being male or female:
Gender Identity
Acquisition of a traditional feminine or masculine gender role:
Gender Typing
People learn social behavior by observing and imitating and by being rewarded or punished:
Social Learning Theory
Children acquire a cultural concept of what it means to be female/male and adjust their behavior accordingly:
Gender Schema Theory
Branch of psych concerned with physical, cognitive, and social change throughout the life span:
Developmental Psychology
Stages are marked by age-specified periods of time:
Discontinuous Development
Relatively even process without distinct stages:
Continuous Development
Fertilized egg or cluster of cells formed during conception by the union of sperm and egg
Zygote
Developing prenatal organism from about 2 weeks though 2 months after conception:
Embryo
Developing prenatal human from 9 weeks after conception to birth:
Fetus
Any drugs, viruses, or other substances that cross the mother’s placenta and can harm the developing embryo or fetus:
Teratogens
Physical and cognitive abnormalities that heavy drinking by a pregnant woman may cause in the developing child:
Fetal Alcohol Syndrome
Newborns curl their fingers around objects when their palms are touched:
Grasping Reflex
Newborn’s tendency when the cheek is stroked to orient toward the stimulus and begin sucking:
Rooting Reflex
Baby sucks objects placed in their mouth or when the lips are touched:
Sucking Reflex
Response when a sudden absence of support producing a feeling of falling:
Moro Reflex
Appearance of taking steps when the baby’s feet touch a flat surface:
Stepping Reflex
Splaying the baby’s toes when the bottom of the foot is stroked:
Babinski Reflex
Decreasing responsiveness to a stimulus that is repeatedly presented; simple form of learning used to study infant cognition:
Habituation
Biological growth processes that enable orderly changes in behavior and are relatively uninfluenced by experience or other environmental factors:
Maturation
Mental concepts or frameworks that organize and interpret information; a theory of cognitive development by Piaget:
