BIS 2C Postlab 3: Body Form in Naegleria Across Environments (Graded A+)

homology - Answer- characters present in organisms because they were inherited from a common ancestor homoplasy - Answer- two structures with the same morphology, where this morphology was not inherited from a common ancestor (evolved multiple times independently) Conflict vs Congruence - Answer- whether or not new data correlates with the hypothesized phylogeny (congruence) or doesn't correlate with the hypothesized phylogeny (conflict) Cladograms - Answer- branch lengths are meaningl...

This is a comprehensive and detailed note for Bis 2c taught by Prof Eisen, Moore And Ledford. Quality stuff!! U'll need it!!

Question 1. Based on figure 4.1, is it correct to state that we understand deep relationships among Eukaryotes? How do we represent ambiguity in branching pattern on phylogenetic trees? Hint: look at figure 1.27. No, we cannot say we understand deep relationships among Eukaryotes because there is a polytomy that represents ambiguity on the phylogenetic tree. No, you cannot define deep relationships amongst eukaryotes because the nodes include polytomies which signifies ambiguity/indefinite...
