HYBRIDS ARE LESS FIT THAN THEIR PARENTS

Evolutionary Perspective

the study of how psychological traits and behaviors have evolved over time to enhance survival and reproductive success.

Natural Selection

the process by which organisms with traits that are better suited to their environment are more likely to survive and reproduce, passing on those advantageous traits to future generations.

Nature “Genes”

the inherent biological and genetic factors that influence an individual's psychological development, traits, behaviors, and cognitive abilities. 

Nurture “Environment”

the environmental influences and experiences that shape an individual's psychological development, behaviors, and cognitive processes.

Twin Studies

Examines similarities and differences between identical (monozygotic) and fraternal (dizygotic) twins to assess the relative influence of genetics and environment on traits and behaviors.

Adoption Studies

Investigates similarities between adopted children and their biological and adoptive families to assess the impact of genetics versus environment on various traits and behaviors.

Family Studies

Analyzes similarities and differences among family members, including parents and siblings, to understand the interplay of genetics and environment in shaping traits and behaviors within a family unit.

Heredity

the transmission of genetic information from biological parents to offspring.

Genetic Predisposition

the inherited likelihood of developing specific traits or conditions due to genetic factors from biological parents.

Genetic Predisposition

the inherited likelihood of developing specific traits or conditions due to genetic factors from biological parents. (ADHD, Bipolar, Autism, Anxiety disorders).

Eugenics

the belief in improving the genetic quality of a human population by controlling reproduction to increase desirable traits and decrease undesirable ones.
