Lecture 2 Flashcards
Why are people genetically different?
Individual variation
Race variation
Subgroup Variation
Are humans once species?
Initially thought No due to skin colour
Cal Von Linne’s theory
That there were 4 classification by skin colour and place of living
What did the skin colour affect in the political world
Pro-Slavery Lobby had a Linnean view on race
Polygeny
many origins of people
Eugenics movement
better genetics than one group ended up in forced steralization
What was wrong with Coon’s hypothesis?
Genes weren’t tested and the evidence wasn’t there
When did ABO typing start and by who
Landsteiner in the early 1900’s
Allozymes/Isoenzymes
enzymes in multiple forms
How can Allozymes/Isoenzymes be seperated?
By electrophoresis, dye to make them coloured
Genetic testing of genes for race started in
1972
What was the percentage of the genetic variation
individual variation: 85%
sub groups variation: 8.3%
race variation: 6.5%
Race is not genetically seen so it is a
social construct
Done again with DNA testing what were the results
The same race is a social concept
