This phylogenetic tree shows how scientists believe the Danes, Chinese, and Tibetans are related based on the analysis of many genes. Use the data about the EPAS1 alleles to add information to the tree. (Assume that there is no interbreeding between the different populations after the lineages split.) Labels can be used once or more than once.

Answer:

Phylogenetic trees can be described as diagrams which represents the evolutionary histories of organisms. The organisms that share more common traits or functions are more closer to one another in the diagram.

The phylogenetic tree in the above diagram shows that the ancestors of Danes, Chinese and Tibetans carried the regular EPAS1 alleles.

According to the tree, the Chinese are more closer to the Tibetans as they carry the Tibetan EPAS1 alleles which the Danes do not carry.
