Question

7. A cladogram (not drawn to scale) for the taxonomic family Hominidae is shown below Next to the cladogram is a table of SNP frequencies for 6 different SNPs sequenced in several individuals in each of the species. The numbers 1 - 10 indicates where along the cladogram a mutation occurred that changed the allele in the common ancestor of all species to a derived allele. The letters A- Frepresent one species from the following list: Homo neanderthalensis, Pan troglodytes (chimpanzees), Homo sapiens (African Bantu). Homo sapiens (European Danish), Homo sapiens (Native American Hopi), and Homo sapiens (Asian Uighurs) COA A 06 A 10 T10 T 10 C1O07 T1O A 10 G10 GIO C10 T 10 C10 T10 5 CLO African Banu A 10 TLO T03 co2s c1 075 CLO Cos A025 ALO COS European Danes G 10 T 10 T10 C 10 6 T 10 CLO Naive American Hopi GIO 10 A 06 C 04 Asian Uighaurs G10 T 10 TLO CLO C D a) Use the SNP data to match the species in the list with an appropriate letter from the cladogram. Two of the species in the list are equivalent on the diagram; either possibility is correct. b) For each of the six SNPs (SNP α, SNP β, SNP γ, SNP δ, SNP ε, and SNPG) indicate the identity of the allele found in the common ancestor. One SNP is undeterminable, write can't tell. For each of the six SNPs (SNP α, SNP ß, SNPy, SNP δ, SNPE, and SNP ζ) identify where along the cladogram a mutation occurred by matching with a number from 1 to 10 One SNP can be matched with either of two numbers. c)
