BIOL 2010 Lecture 2: Phylogenetic Trees

True or False: When there are 70 species in a genus and you want to infer a phylogenetic tree for this group, there are more possible rooted phylogenetic trees as your answer than there are atoms in the Universe (approximately 10⁸⁰ atoms are thought to exist in the Universe).

What is a general path to get from dna sequences to phylogenetic trees?

Analysis based on two individual genes (gene trees) may imply two different phylogenetic relationships amaong a group of species. List three possible reasons for this (1), and explain how one of them works (2) and how can you determine which one is correct (3)
