caption: The following questions refer to the table below, which compares the % sequence homology of four different Parts (2 introns and 2 exons) of a gene that is found in five different eukaryotic species. Each part is numbered to indicate its distance from the promoter (e.g., Intron I is that 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 a. distinguishing introns from exons. b. determining degree of sequence homology. c. selecting appropriate genes for comparison among species. d. inferring evolutionary relatedness from the number of sequence differences.
