ANT 1 Lecture Notes - Lecture 4: Human Genetic Variation, Sickle-Cell Disease, Human Skin Color
Document Summary
If you know a substantial portion of someone"s genome it is possible to accurately determine from which major geographical regions (e. g. , europe) he/she originates. True: within switzerland it is possible to distinguish german-, french-, and italian-speaking individuals from each other based on their genotypes at hundreds of thousands of snps. : true; geographically close together, patterns reasonably well, small differences in frequency: when genetic loci are used to identify clusters (groups) of humans, the same clusters are found regardless of which particular loci are used. True; there is a lot of genetic variation in sub-saharan africa, more than in other geographic areas: of the six fully-sequenced human genomes available in 2010 the two from americans of. European descent share more snps with a korean individual than they share with each other. If you know a person"s ancestry, you can fairly accurately infer their genotype.
