Question

Here is some mitochondrial DNA sequence data from a study of a representative individual from each of several different human groups and a chimpanzee. Seven hundred base pairs were sequenced in total. Only the nucleotide sites that vary among the groups are represented in the table (for example, positions 1-17 are identical for the chimpanzee and all the human groups). Which of the phylogenies below best represents the relationships among chimps and Groups a through d, based on the data in the table? Chimp Chimp Chimp Chimp D. Chimp O A. Phylogeny A O B. Phylogeny B O C. Phylogeny C O D. Phylogeny D O E. Phylogeny E

Explanation / Answer

Answer

B. Phylogeny B

Explanation : if we compare group b and d then there most of the nucleotide sequences are similar as compared with others (total 11 positions are identical). Hence the two must be placed at same position under same level
