Genetics & Behaviors Flashcards
Learned behaviors
Not based on heredity but based on experience and environment
Adaptive value
The extent to which a trait or behavior positively benefits species by influencing the evolutionary fitness of species, thus leading to the adaptations through natural selection
Nature vs nurture
Debate regarding the relative contribution of genetics (nature) and environment (nurture) to an individual’s traits
(3) studies regarding nature vs nurture
Twin studies
Family studies
Adoption studies
Family studies
Looks at relative frequency of a trait within a family compared to the general population
Concordance rates refer to
The likelihood that both twins exhibit the same trait
Twin studies
Compares concordance rates for a trait between monozygotic (identical) and dizygotic (fraternal) twins
Adoptive studies
Compare similarities between adopted children and their adoptive parents, relative to similarities with their biological parents
Innate behavior
Result of evolution
Seen in all individuals regardless of environment and experience
