NATURE VERSUS NURTURE
What is the debate and why should we care?
What are some of the things being debated right now?
How do we establish hereditability?
twin studies: concordance rates MZ vs. DZ twins
what are some challenges faced by twin studies
Caution: What do we really inherit? Can we determine hereditability for an individual?
GENETICS: just the basics
GENES are structures that provide the biological blueprintFor who we are: physically and psychologically, they do so by directing proteins
Most genes are arranged on 23 pairs of CHROMOSOMES, foundin every cell
Chromosomes are identified by number, 1-22, except…???
Genes are made up of DNA, a twisted ladder of bases:
adenine thymine guanine cytosine
The order of these 4 bases constitutes our GENETIC CODE
Facts about Genes
Most genes are paired because the chomosomes they’re on are paired
Genes may be DOMINANT or RECESSIVE for a trait
Other genes blend their effects: a good example is blood type (AB)
Some traits are determined by a single gene pair (e.g. eye color)
Other traits are POLYGENIC
Epigenetics
the study of the environmental influences that turn genes on and off
This alters genetic expression – one’s phenotype
Can thoughts and beliefs affect gene activity?
