5 Matching questions

  1. Basal angiosperms
  2. Form genus
  3. Taxon
  4. Natural system of classification
  5. Cladogram
  1. a classification based on evolutionary, phylogenetic relationships
  2. b genus based on a character that is not a reliable indicator of evolutionary relationships, unrelated groups get grouped together
  3. c a term that refers to any taxonomic group such as species, genus, family, etc...
    Type specimen: a single specimen that is the absolute standard for the species and its scientific name
  4. d the several clades of angiosperms that arose before the rest of the angiosperms diverged into the monocots and eudicots
  5. e a branching diagram sowing the phylogenetic relationships of several or many taxa

5 Multiple choice questions

  1. : a group of organisms that can interbreed and produce fertile offspring
  2. a trait which is shared (a symmorphy) between two or more taxa, but which is also shared with other taxa which have an earlier last common ancestor with the taxa under consideration
  3. 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
  4. : a clade that contains an ancestral taxon, and several but not all its descendants
  5. features that are the phenotypic expression of homologous genes, those related by descent from common ancestoral genes

5 True/False questions

  1. Apomorphya 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.

          

  2. Inheritance of acquired characteristicsfeatures that resemb;e eachother but are not based on homologous genes, those related by descent from common ancestral genes

          

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

          

  4. Phylogenythe 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. Analogous featuresfeatures that resemb;e eachother but are not based on homologous genes, those related by descent from common ancestral genes
