5 Written questions

5 Matching questions

  1. Homologous features
  2. Natural system of classification
  3. Form genus
  4. Eudicots
  5. Parsimony
  1. a genus based on a character that is not a reliable indicator of evolutionary relationships, unrelated groups get grouped together
  2. b features that are the phenotypic expression of homologous genes, those related by descent from common ancestoral genes
  3. c the clade of angiosperms that contains most species formally known as dicots, broad leaves and pollen with more than one germination pore
  4. d classification based on evolutionary, phylogenetic relationships
  5. e the concept of minimum complexity: the simplest hypothesis that explains several observation is the most parsimonious. In cladistics, a cladogram with the least number of steps is the most parsimonious

5 Multiple choice questions

  1. during divergent evolutiona common ancstor gives rise to two or more groups, in a cladogram, it is node that gives rise to the taxa being studied
  2. where a common ancestor is located on a cladogram
  3. features that resemb;e eachother but are not based on homologous genes, those related by descent from common ancestral genes
  4. a trait that is shared ("symmorphy") by two or more taxa and their most recent common ancestor, whose ancestor in turn does not possess the trait.
  5. the binomial name of a species

5 True/False questions

  1. Basal angiospermsgenus based on a character that is not a reliable indicator of evolutionary relationships, unrelated groups get grouped together

          

  2. symplesiomorphya trait that is shared ("symmorphy") by two or more taxa and their most recent common ancestor, whose ancestor in turn does not possess the trait.

          

  3. Species: a group of organisms that can interbreed and produce fertile offspring

          

  4. Cladograma branching diagram sowing the phylogenetic relationships of several or many taxa

          

  5. Artificial classification systemclassification based on evolutionary, phylogenetic relationships
