  • 1. 
    This phenomena can be induced in those responsible for the horizontal elements of this phylogeny

  • mitosis
  • point mutations
  • S phase of the cell cycle
  • endosymbiosis

  • 2. 
    If cladistics were used to build a phylogenetic tree of cats, this would be the most appropriate outgroup

  • tiger
  • leopard
  • wolf
  • domestic cat

  • 3. 
    To construct a phylogenetic tree in order to apply parsimony, choose

  • tree with fewest branch points
  • tree representing fewest evolutionary changes either in morphology or DNA sequences
  • tree in which branch points are based on as many shared characters possible
  • tree assuming all evolutionary changes with equal probability

  • 4. 
    This is used to know the phylogeny

  • mRNA
  • rRNA
  • DNA
  • none of these

  • 5. 
    On the basis of cladistics, this eukaryotic kingdom is polyphyletic and hence unacceptable

  • Monera
  • Protista
  • Animalia
  • Fungi

  • 6. 
    Possessing four appendages when comparing mammals with birds is

  • a character used to sort bird species
  • example of analogy rather than homology
  • a shared derived character
  • a shared ancestral character

  • 7. 
    Pick the incorrect statement concerning the terminologies of phylogenetics

  • branches are the lines in the tree
  • tips of the branches have long lost sequences or species
  • node indicate inferred ancestor of extant taxa
  • connecting point joining two adjacent branches is a node

  • 8. 
    This is not a vestigial organ in man

  • coccyx
  • nails
  • third molar
  • homologous

  • 9. 
    Pick the incorrect option for the blank

  • physical separation methods
  • proteomes
  • genomes
  • gene families

  • 10. 
    This is incorrect about the merits of molecular data for Phylogenetics study

  • sampling bias is involved
  • with the help of molecular data more robust and clear-cut phylogenetic tree can be constructed
  • much easier to obtain in comparison to fossil records
  • more in number compared to fossil records
