Phylogeny Flashcards
1
Q
What does a phylogenetic tree show?
A
Inferred evolutionary relationships among various biological species based upon similarities and differences in their physical or genetic characteristics
2
Q
What does a cladogram show?
A
Relative order of common ancestry
3
Q
What are the advantages of a cladogram?
A
Does not reduced sequence information to a single number
4
Q
What are the disadvantages of a cladogram?
A
Cannot infer anything about evolutionary time
No information on branch lengths
5
Q
How do you check the reliability of phylogeny?
A
Use bootstap, different algorithms, build a consensus among various methods, compare other DNA sequences with the same species
