Part E Your molecular clock model resembles another branching chart, the phylogenetic chart, which you’ve used in this unit. Review the sample phylogenetic chart. What types of data are used to build a phylogenetic chart? How do phylogenetic charts differ from molecular models, such as the molecular clock model?

The phylogenetic graph uses several types of variables to be formed, while other models use only one type of variable.

Explanation:

To create a phylogenetic chart, matrices with data on the studied species are used. These data are composed of morphological, chemical and / or genetic information that allow a detailed investigation about the ancestry of each species, in addition to allowing the correct grouping based on this ancestry and evolution.

A phylogenetic graph is different from other molecular models due to the number of data considered by it, since other models, such as the molecular clock, for example, only consider genetic based information.

the correct answer, according to e2020, is the second choice there is an occluded front in region a and a cold front in region b.
