ANT203H5 Chapter Notes - Chapter 14: Intelligence Quotient, Heritability, Negroid
Document Summary
The least amount of variation - the most amount of variation (existing in humans: physical characteristics (ex. hair colour, less observed characteristics (teeth, variation at the molecular level. Allele frequencies, what are genotypes and phenotypes = simple traits. *biological anthropologists study variation in terms of evolutionary forces and biocultural adaptations . * but individuals often discuss variation as race and ethnicity. People tend to classify and reduce variation by using averages or stereotypes . 2 goals of this chapter: look at different types of variation, look at the global patterns of human genetic diversity. Can exist in terms of physical traits but also in terms of biochemical traits ex. diff blood groups (a, b, o, ab) A lot of info has been found about genetic traits by looking at red blood cells. Rbc polymorphism include blood types and protein and enzyme types. Polymorphism = genetic trait where at least 2 alleles have a frequency greater than 1%
