Chapter 5 : Inferring Phylogeny

Question 1

How can evolutionary biology address issues using phylogenetic analysis? Example: the HIV strains that infected 400 children in Libya.

Answer 1

Differences in the genome sequence can be used to create a phylogeny of the virus. The phylogeny can then show the relationships between the infections in the children and other known strains of HIV.

Question 2

Sequence divergence

Answer 2

Greater differences between DNA sequences.
