• Neighbor-joining chooses the sequences that should be joined to give the best least squares estimates of the branch lengths that most closely reflect the actual distances between the sequences.
  ক

  True

  খ

  False
• Which of the following is untrue regarding the neighbor-joining method?
  ক

  It is very much like the Fitch-Margoliash method

  খ

  It is totally dissimilar than the Fitch-Margoliash method

  গ

  It is especially suitable when the rate of evolution of the separate lineages under consideration varies

  ঘ

  When the branch lengths of trees of known topology are allowed to vary in a manner that simulates varying levels of evolutionary change, it is the most reliable method
• Which of the following is untrue regarding the Distance analysis programs in PHYLIP?
  ক

  FITCH estimates a phylogenetic tree assuming additivity of branch lengths

  খ

  FITCH uses the Fitch-Margoliash method

  গ

  FITCH assumes a molecular clock but KITSCH does not

  ঘ

  NEIGHBOR estimates phylogenies using the neighbor-joining or unweighted pair group method with arithmetic mean (UPGMA)
• Which of the following is untrue regarding the distance methods?
  ক

  The sequence pairs that have the largest number of sequence changes between them are termed ‘neighbors’

  খ

  On a tree, these sequences share a node or common ancestor position and are each joined to that node by a branch

  গ

  It produces a phylogenetic tree of the group

  ঘ

  It employs the number of changes between each pair in a group of sequences
• Parsimony can give ________ information when rates of sequence change _______ in the different branches of a tree that are represented by the sequence data.
  ক

  misleading, vary

  খ

  useful, change

  গ

  misleading, are constant

  ঘ

  sometimes contradicting, are constant
• PROTPARS counts the minimum number of mutations to change a codon for the first amino acid into a codon for the second amino acid, but only scores those mutations in the mutational path that actually change the amino acid.
  ক

  True

  খ

  False

  খ

  It minimizes the number of steps required to generate the observed variation in the sequences

  গ

  The method is also sometimes referred to as the minimum evolution method

  ঘ

  Only a pairwise sequence alignment is required to predict which sequence positions are likely to correspond
