The Next Questions Refer to the Following Table, Which Compares

question 10

Multiple Choice

The next questions refer to the following table, which compares the % 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 (e.g., 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.
% Sequence Homology

-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.
