Answer
(e) Genetic homology (d) Phage typing (a) Protein profiling (f) Numerical taxonomy (b) DNA hybridization (c) G–C content
Work Step by Step
The following are the special contemporary methods that may help in determining the evolutionary relatedness and its definition:
Genetic homology- Similarity of DNA among different organisms provides a measure of their relatedness
Phage typing-Employs the use of bacteriophages to determine similarities among different bacteria
Protein profiling- Polyarylamide gel electrophoresis is used to resolve whether the same proteins are present in different organisms
Numerical taxonomy- A large number of characteristics are compared and grouped according to the percentage of shared characteristics
DNA hybridization- Double-stranded DNA from two organisms is split apart with the split strands being allowed to combine; the degree of matching gives an idea of the amount of genetic homology between different organisms
G–C content- The relative percentages of bases of DNA are a measure of relatedness between two different organisms
