Describe maximum parsimony Flashcards
What is the principle of maximum parsimony?
The principle of maximum parsimony states that the simplest explanation or path, requiring the fewest evolutionary changes, is preferred when constructing phylogenetic trees.
True or False: Maximum parsimony aims to minimize the number of character changes in a phylogenetic tree.
True
Fill in the blank: Maximum parsimony is often used in __________ analysis.
phylogenetic
Which of the following methods is commonly associated with maximum parsimony? A) Distance methods B) Cladistics C) Bayesian inference
B) Cladistics
What type of data is typically used in maximum parsimony analysis?
Molecular data, such as DNA or protein sequences, and morphological characteristics.
Describe one limitation of maximum parsimony.
One limitation is that it may oversimplify complex evolutionary histories, potentially leading to incorrect phylogenetic conclusions.
True or False: Maximum parsimony can only be applied to molecular data.
False
What is the goal when applying maximum parsimony in phylogenetic analysis?
To reconstruct the most likely evolutionary relationships among species based on shared characteristics.
Multiple choice: What does maximum parsimony minimize? A) Genetic diversity B) Time of divergence C) Number of character changes
C) Number of character changes
In maximum parsimony, how is a tree evaluated?
A tree is evaluated based on the total number of character changes it requires, with fewer changes being preferred.
