Biological bases of Behaviour: Endocrine System
- Heredity and behaviour: Is it All in the genes?
- Basic principles of Genetics
- Chromosomes and genes
- Genotype VS. phenotype: genetic
makeup- phenotype- genotype is
put together
- Polygenic Inheritance- characteristics
that are influenced by more than one
pair of genes
- Investing Hereditary Influence: Research Methods
- Family studies:
- Twin studies: Identical and fraternal
- Adoption studies: relation between adopted child and biological and adoptive parents
- Cutting the edge:
Genetic mapping-
determined location and
chemical sequence of
specific genes on specific
chromosomes
- Evolutionary bases of behaviour
- Darwin's Insights
- Fitness- reproductive success of an
individual organism relative to the average
reproductive success in the population
- Natural selection- heritable
characteristics that provide a
survival or reproductive
advantage are more likely than
alternative characteristics to be
passed on to subsequent
generations and thus come to be
"selected" over time.
- Subsequent Refinements to evolutionary Theory
- mutation- spontaneous, heritable change in a piece of DNA that
occurs in an individual organism
- Adaptation- inherited characteristic that increased in a populaation
becuase it helped solve a problem of survival or reproduction during
the time it emerged.
