Chapter 2- Current Paradigms In Psychopathology Flashcards
Carriers of genetic information
Genes
A conceptual framework or approach within which a scientists works.
Paradigm
Several genes, operating at different times during the course if development, turning themselves in and off as they interact with a person’s environment
Polygenic
Extent to which variability in a particular behavior or disorder in a population can be accounted for by genetic factors
Heritability
Factors that family members have in common
Shared environment
Distinct factors
Nonshared environment (unique environment)
Study of the degree to which genes and environmental factors influence behavior
Behavior genetics
Total genetic makeup of an individual
Genotype
Observable behavioral characteristics
Phenotype
A study that seeks to identify particular genes and their function
Molecular genetics
Different forms of the same gene
Alleles
Difference in DNA sequence on an gene that has occurred in a population
Polymorphism
Differences between people in a single nucleotide
Single nucleotide polymorphism (SNPs)
Abnormal copy of one or more sections of DNA within the genes
Copy number variations (CNVs)
A given person’s sensitivity to an environmental event is influences by genes
Gene-environment interactions
Study on how the environment can alter gene expression
