#Question id: 8702


The question refers to the following table, which compares the percent sequence homology of four different parts (two introns and two exons) of a gene that is found in five different eukaryotic species. Each part is numbered to indicate its distance from the promoter (for example, Intron I is the one closest to the promoter). The data reported for species A were obtained by comparing DNA from one member of species A to another member of species A.

Regarding these sequence homology data, the principle of maximum parsimony would be applicable in ________.

#SCPH06 I Botany
  1. distinguishing introns from exons
  2. determining degree of sequence homology
  3. selecting appropriate genes for comparison among species
  4. inferring evolutionary relatedness from the number of sequence differences
