Module 2-Lecture 5

Question 1

Can we use phylogenies to represent relationships between populations?

Answer 1

Yes, but only if they are GENETICALLY ISOLATED, NO GENE FLOW

Question 2

If there is no gene flow, what does each population form?

Answer 2

Monophyletic group

Question 3

What is gene flow?

Answer 3

Migration between populations

Question 4

If many different groups have the same most recent common ancestor, what can we infer?

Answer 4

There was pathogen gene flow/migration between these groups or the phylogenetic tree is not correct
