Debate surrounding the relative importance of heredity (nature) and environment (nurture) in determining behavior.
NATURE NURTUREArgue that hereditary factors play the major role in determining such characteristics as our intelligence, personality, and temperament.
Argue that environment including our daily experiences, up bringing, and education are the major determinates of these characteristics.
Genetics• Study of how traits are transmitted from one generation to
the next
Traits• Characteristics on which organisms differ
Genes• Control the transmission of traits; found on the
chromosomes
Heredity• Transmission of traits from one generation to the
next
Pairs of threadlike bodies within the cell nucleus that contain the genes
Humans have 23 pairs in every normal cell
Main ingredient is DNA
Complex molecule in a double-helix configuration that is the main ingredient of chromosomes and forms the code for all genetic information
Dominant Member of a gene pair
that controls the appearance of a certain trait
For our example: B
Recessive Member of a gene pair
that can control the appearance of a certain trait only if it is paired with another recessive gene
For our example: b
Process by which several genes interact to produce a certain trait; responsible for our most important traits
Not all effects will be immediate or fully apparent
Some may not show up based on behavior
