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
