QUESTIONS Question 13-1: What types of genetic data and analysis methods would be required to solve the question of whether peopling of the Americas involved one or three dispersal events? Question 13-2: What would be the key advantages and disadvantages of using genomewide genotype data as opposed to high-resolution sequence information from a few selected loci and sequence data from the entire genome in addressing questions of genetic origins of the New World and Remote Oceanian populations? Question 13-3: Suppose an ancient DNA study on the remains of Kennewick Man would recover mtDNA sequence from haplogroup E and nuclear DNA signatures similar to modern-day entral Asian populations. How would this evidence change our current interpretation of Native American origins?Explanation / Answer
Mapping the appearance and frequency of genetic markers in this population will let us now how the different populations of America are related at the genotypic level. This can be done by SNP genome wide genotyping.
Another useful analysis for resolving when occurred the dispersal events is haplogroup subclades based on ancient DNA studies.
