Chapter 20
Phylogeny
Learning Objectives:
3.A.1: DNA, and in some cases RNA, is the primary source of heritable information.
3.A.4: The inheritance pattern of many traits cannot be explained by simple Mendelian genetics.
3.C.1: Changes in genotype can result in changes in phenotype.
3.C.3: Viral replication results in genetic variation and viral infection can introduce genetic variation into the hosts.

Scientific Skills Exercise:
Using protein sequence data to test test an evolutionary hypothesis
Did aphids acquire their ability to make carotenoids through horizontal gene transfer?

Complete in Notes.
As you complete test, mark questions with:
a star (I know this),
a checkmark (I might know this),
or a question mark (I don't know, I guessed).
Self-correct.
Write validations/corrections for checkmarks, question marks, and missed stars (oops).
