PSY-1200 Chapter Notes -Francis Galton, Gene Expression, Zygosity
Document Summary
Nature: the contributions of heredity to our physical structure and behaviors. Nurture: the contributions of environmental factors and experience to our physical structure and behaviors. Earlier scholars talked in terms of nature vs. nurture and debated relative contributions of each to a particular behavior (either/or approach), but we know that they are closely intertwined. Nature vs. nurture phrase coined by francis galton. Said that intellectual skills were largely the result of genetic inheritance. Every cell in your body (with the exception of red blood cells and sex cells) contains 2 complete copies of the human genome. Genotype: an individual"s pro le of alleles (genetic code) Each parent contributes a set of 23 chromosomes (for a total of 46), which are composed of many molecules of dna. Each small segment of dna is a gene. Each gene contains instructions for making a particular type of protein (protein in uences phenotype)
