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?
