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 blueprint For who we are: physically and psychologically, they do so by directing proteins Most genes are arranged on 23 pairs of CHROMOSOMES, found in 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? http://www.youtube.com/watch?v=Fj4d-9Jgl6g&feature=related http://www.youtube.com/watch?v=ylmwoJDYGjk&feature=related
